      • batchExecuteStatementAsync

        public Future<BatchExecuteStatementResult> batchExecuteStatementAsync(BatchExecuteStatementRequest request)
        Description copied from interface: AmazonDynamoDBAsync

        This operation allows you to perform batch reads or writes on data stored in DynamoDB, using PartiQL. Each read statement in a BatchExecuteStatement must specify an equality condition on all key attributes. This enforces that each SELECT statement in a batch returns at most a single item. For more information, see Running batch operations with PartiQL for DynamoDB .

        The entire batch must consist of either read statements or write statements, you cannot mix both in one batch.

        A HTTP 200 response does not mean that all statements in the BatchExecuteStatement succeeded. Error details for individual statements can be found under the Error field of the BatchStatementResponse for each statement.

        Specified by:
        batchExecuteStatementAsync in interface AmazonDynamoDBAsync
        Returns:
        A Java Future containing the result of the BatchExecuteStatement operation returned by the service.

      • batchGetItemAsync

        public Future<BatchGetItemResult> batchGetItemAsync(BatchGetItemRequest request)
        Description copied from interface: AmazonDynamoDBAsync

        The BatchGetItem operation returns the attributes of one or more items from one or more tables. You identify requested items by primary key.

        A single operation can retrieve up to 16 MB of data, which can contain as many as 100 items. BatchGetItem returns a partial result if the response size limit is exceeded, the table's provisioned throughput is exceeded, more than 1MB per partition is requested, or an internal processing failure occurs. If a partial result is returned, the operation returns a value for UnprocessedKeys. You can use this value to retry the operation starting with the next item to get.

        If you request more than 100 items, BatchGetItem returns a ValidationException with the message "Too many items requested for the BatchGetItem call."

        For example, if you ask to retrieve 100 items, but each individual item is 300 KB in size, the system returns 52 items (so as not to exceed the 16 MB limit). It also returns an appropriate UnprocessedKeys value so you can get the next page of results. If desired, your application can include its own logic to assemble the pages of results into one dataset.

        If none of the items can be processed due to insufficient provisioned throughput on all of the tables in the request, then BatchGetItem returns a ProvisionedThroughputExceededException. If at least one of the items is successfully processed, then BatchGetItem completes successfully, while returning the keys of the unread items in UnprocessedKeys.

        If DynamoDB returns any unprocessed items, you should retry the batch operation on those items. However, we strongly recommend that you use an exponential backoff algorithm. If you retry the batch operation immediately, the underlying read or write requests can still fail due to throttling on the individual tables. If you delay the batch operation using exponential backoff, the individual requests in the batch are much more likely to succeed.

        For more information, see Batch Operations and Error Handling in the Amazon DynamoDB Developer Guide.

        By default, BatchGetItem performs eventually consistent reads on every table in the request. If you want strongly consistent reads instead, you can set ConsistentRead to true for any or all tables.

        In order to minimize response latency, BatchGetItem may retrieve items in parallel.

        When designing your application, keep in mind that DynamoDB does not return items in any particular order. To help parse the response by item, include the primary key values for the items in your request in the ProjectionExpression parameter.

        If a requested item does not exist, it is not returned in the result. Requests for nonexistent items consume the minimum read capacity units according to the type of read. For more information, see Working with Tables in the Amazon DynamoDB Developer Guide.

      • batchWriteItemAsync

        public Future<BatchWriteItemResult> batchWriteItemAsync(BatchWriteItemRequest request)
        Description copied from interface: AmazonDynamoDBAsync

        The BatchWriteItem operation puts or deletes multiple items in one or more tables. A single call to BatchWriteItem can transmit up to 16MB of data over the network, consisting of up to 25 item put or delete operations. While individual items can be up to 400 KB once stored, it's important to note that an item's representation might be greater than 400KB while being sent in DynamoDB's JSON format for the API call. For more details on this distinction, see Naming Rules and Data Types.

        BatchWriteItem cannot update items. If you perform a BatchWriteItem operation on an existing item, that item's values will be overwritten by the operation and it will appear like it was updated. To update items, we recommend you use the UpdateItem action.

        The individual PutItem and DeleteItem operations specified in BatchWriteItem are atomic; however BatchWriteItem as a whole is not. If any requested operations fail because the table's provisioned throughput is exceeded or an internal processing failure occurs, the failed operations are returned in the UnprocessedItems response parameter. You can investigate and optionally resend the requests. Typically, you would call BatchWriteItem in a loop. Each iteration would check for unprocessed items and submit a new BatchWriteItem request with those unprocessed items until all items have been processed.

        For tables and indexes with provisioned capacity, if none of the items can be processed due to insufficient provisioned throughput on all of the tables in the request, then BatchWriteItem returns a ProvisionedThroughputExceededException. For all tables and indexes, if none of the items can be processed due to other throttling scenarios (such as exceeding partition level limits), then BatchWriteItem returns a ThrottlingException.

        If DynamoDB returns any unprocessed items, you should retry the batch operation on those items. However, we strongly recommend that you use an exponential backoff algorithm. If you retry the batch operation immediately, the underlying read or write requests can still fail due to throttling on the individual tables. If you delay the batch operation using exponential backoff, the individual requests in the batch are much more likely to succeed.

        For more information, see Batch Operations and Error Handling in the Amazon DynamoDB Developer Guide.

        With BatchWriteItem, you can efficiently write or delete large amounts of data, such as from Amazon EMR, or copy data from another database into DynamoDB. In order to improve performance with these large-scale operations, BatchWriteItem does not behave in the same way as individual PutItem and DeleteItem calls would. For example, you cannot specify conditions on individual put and delete requests, and BatchWriteItem does not return deleted items in the response.

        If you use a programming language that supports concurrency, you can use threads to write items in parallel. Your application must include the necessary logic to manage the threads. With languages that don't support threading, you must update or delete the specified items one at a time. In both situations, BatchWriteItem performs the specified put and delete operations in parallel, giving you the power of the thread pool approach without having to introduce complexity into your application.

        Parallel processing reduces latency, but each specified put and delete request consumes the same number of write capacity units whether it is processed in parallel or not. Delete operations on nonexistent items consume one write capacity unit.

        If one or more of the following is true, DynamoDB rejects the entire batch write operation:

        • One or more tables specified in the BatchWriteItem request does not exist.

        • Primary key attributes specified on an item in the request do not match those in the corresponding table's primary key schema.

        • You try to perform multiple operations on the same item in the same BatchWriteItem request. For example, you cannot put and delete the same item in the same BatchWriteItem request.

        • Your request contains at least two items with identical hash and range keys (which essentially is two put operations).

        • There are more than 25 requests in the batch.

        • Any individual item in a batch exceeds 400 KB.

        • The total request size exceeds 16 MB.

        • Any individual items with keys exceeding the key length limits. For a partition key, the limit is 2048 bytes and for a sort key, the limit is 1024 bytes.

      • createBackupAsync

        public Future<CreateBackupResult> createBackupAsync(CreateBackupRequest request)
        Description copied from interface: AmazonDynamoDBAsync

        Creates a backup for an existing table.

        Each time you create an on-demand backup, the entire table data is backed up. There is no limit to the number of on-demand backups that can be taken.

        When you create an on-demand backup, a time marker of the request is cataloged, and the backup is created asynchronously, by applying all changes until the time of the request to the last full table snapshot. Backup requests are processed instantaneously and become available for restore within minutes.

        You can call CreateBackup at a maximum rate of 50 times per second.

        All backups in DynamoDB work without consuming any provisioned throughput on the table.

        If you submit a backup request on 2018年12月14日 at 14:25:00, the backup is guaranteed to contain all data committed to the table up to 14:24:00, and data committed after 14:26:00 will not be. The backup might contain data modifications made between 14:24:00 and 14:26:00. On-demand backup does not support causal consistency.

        Along with data, the following are also included on the backups:

        • Global secondary indexes (GSIs)

        • Local secondary indexes (LSIs)

        • Streams

        • Provisioned read and write capacity

        Specified by:

      • createGlobalTableAsync

        public Future<CreateGlobalTableResult> createGlobalTableAsync(CreateGlobalTableRequest request)
        Description copied from interface: AmazonDynamoDBAsync

        Creates a global table from an existing table. A global table creates a replication relationship between two or more DynamoDB tables with the same table name in the provided Regions.

        This documentation is for version 2017年11月29日 (Legacy) of global tables, which should be avoided for new global tables. Customers should use Global Tables version 2019年11月21日 (Current) when possible, because it provides greater flexibility, higher efficiency, and consumes less write capacity than 2017年11月29日 (Legacy).

        To determine which version you're using, see Determining the global table version you are using. To update existing global tables from version 2017年11月29日 (Legacy) to version 2019年11月21日 (Current), see Upgrading global tables.

        If you want to add a new replica table to a global table, each of the following conditions must be true:

        • The table must have the same primary key as all of the other replicas.

        • The table must have the same name as all of the other replicas.

        • The table must have DynamoDB Streams enabled, with the stream containing both the new and the old images of the item.

        • None of the replica tables in the global table can contain any data.

        If global secondary indexes are specified, then the following conditions must also be met:

        • The global secondary indexes must have the same name.

        • The global secondary indexes must have the same hash key and sort key (if present).

        If local secondary indexes are specified, then the following conditions must also be met:

        • The local secondary indexes must have the same name.

        • The local secondary indexes must have the same hash key and sort key (if present).

        Write capacity settings should be set consistently across your replica tables and secondary indexes. DynamoDB strongly recommends enabling auto scaling to manage the write capacity settings for all of your global tables replicas and indexes.

        If you prefer to manage write capacity settings manually, you should provision equal replicated write capacity units to your replica tables. You should also provision equal replicated write capacity units to matching secondary indexes across your global table.

        Specified by:
        createGlobalTableAsync in interface AmazonDynamoDBAsync

      • createTableAsync

        public Future<CreateTableResult> createTableAsync(CreateTableRequest request)
        Description copied from interface: AmazonDynamoDBAsync

        The CreateTable operation adds a new table to your account. In an Amazon Web Services account, table names must be unique within each Region. That is, you can have two tables with same name if you create the tables in different Regions.

        CreateTable is an asynchronous operation. Upon receiving a CreateTable request, DynamoDB immediately returns a response with a TableStatus of CREATING. After the table is created, DynamoDB sets the TableStatus to ACTIVE. You can perform read and write operations only on an ACTIVE table.

        You can optionally define secondary indexes on the new table, as part of the CreateTable operation. If you want to create multiple tables with secondary indexes on them, you must create the tables sequentially. Only one table with secondary indexes can be in the CREATING state at any given time.

        You can use the DescribeTable action to check the table status.

      • createTableAsync

        public Future<CreateTableResult> createTableAsync(CreateTableRequest request,
 AsyncHandler<CreateTableRequest,CreateTableResult> asyncHandler)
        Description copied from interface: AmazonDynamoDBAsync

        The CreateTable operation adds a new table to your account. In an Amazon Web Services account, table names must be unique within each Region. That is, you can have two tables with same name if you create the tables in different Regions.

        CreateTable is an asynchronous operation. Upon receiving a CreateTable request, DynamoDB immediately returns a response with a TableStatus of CREATING. After the table is created, DynamoDB sets the TableStatus to ACTIVE. You can perform read and write operations only on an ACTIVE table.

        You can optionally define secondary indexes on the new table, as part of the CreateTable operation. If you want to create multiple tables with secondary indexes on them, you must create the tables sequentially. Only one table with secondary indexes can be in the CREATING state at any given time.

        You can use the DescribeTable action to check the table status.

        Specified by:
        createTableAsync in interface AmazonDynamoDBAsync
        Parameters:
        request - Represents the input of a CreateTable operation.
        asyncHandler - Asynchronous callback handler for events in the lifecycle of the request. Users can provide an implementation of the callback methods in this interface to receive notification of successful or unsuccessful completion of the operation.
        Returns:
        A Java Future containing the result of the CreateTable operation returned by the service.

      • deleteItemAsync

        public Future<DeleteItemResult> deleteItemAsync(DeleteItemRequest request)
        Description copied from interface: AmazonDynamoDBAsync

        Deletes a single item in a table by primary key. You can perform a conditional delete operation that deletes the item if it exists, or if it has an expected attribute value.

        In addition to deleting an item, you can also return the item's attribute values in the same operation, using the ReturnValues parameter.

        Unless you specify conditions, the DeleteItem is an idempotent operation; running it multiple times on the same item or attribute does not result in an error response.

        Conditional deletes are useful for deleting items only if specific conditions are met. If those conditions are met, DynamoDB performs the delete. Otherwise, the item is not deleted.

        Specified by:
        deleteItemAsync in interface AmazonDynamoDBAsync
        Parameters:
        request - Represents the input of a DeleteItem operation.
        Returns:
        A Java Future containing the result of the DeleteItem operation returned by the service.

      • deleteResourcePolicyAsync

        public Future<DeleteResourcePolicyResult> deleteResourcePolicyAsync(DeleteResourcePolicyRequest request)
        Description copied from interface: AmazonDynamoDBAsync

        Deletes the resource-based policy attached to the resource, which can be a table or stream.

        DeleteResourcePolicy is an idempotent operation; running it multiple times on the same resource doesn't result in an error response, unless you specify an ExpectedRevisionId, which will then return a PolicyNotFoundException.

        To make sure that you don't inadvertently lock yourself out of your own resources, the root principal in your Amazon Web Services account can perform DeleteResourcePolicy requests, even if your resource-based policy explicitly denies the root principal's access.

        DeleteResourcePolicy is an asynchronous operation. If you issue a GetResourcePolicy request immediately after running the DeleteResourcePolicy request, DynamoDB might still return the deleted policy. This is because the policy for your resource might not have been deleted yet. Wait for a few seconds, and then try the GetResourcePolicy request again.

        Specified by:
        deleteResourcePolicyAsync in interface AmazonDynamoDBAsync
        Returns:

      • deleteTableAsync

        public Future<DeleteTableResult> deleteTableAsync(DeleteTableRequest request)
        Description copied from interface: AmazonDynamoDBAsync

        The DeleteTable operation deletes a table and all of its items. After a DeleteTable request, the specified table is in the DELETING state until DynamoDB completes the deletion. If the table is in the ACTIVE state, you can delete it. If a table is in CREATING or UPDATING states, then DynamoDB returns a ResourceInUseException. If the specified table does not exist, DynamoDB returns a ResourceNotFoundException. If table is already in the DELETING state, no error is returned.

        For global tables, this operation only applies to global tables using Version 2019年11月21日 (Current version).

        DynamoDB might continue to accept data read and write operations, such as GetItem and PutItem, on a table in the DELETING state until the table deletion is complete. For the full list of table states, see TableStatus.

        When you delete a table, any indexes on that table are also deleted.

        If you have DynamoDB Streams enabled on the table, then the corresponding stream on that table goes into the DISABLED state, and the stream is automatically deleted after 24 hours.

        Use the DescribeTable action to check the status of the table.

      • describeLimitsAsync

        public Future<DescribeLimitsResult> describeLimitsAsync(DescribeLimitsRequest request)
        Description copied from interface: AmazonDynamoDBAsync

        Returns the current provisioned-capacity quotas for your Amazon Web Services account in a Region, both for the Region as a whole and for any one DynamoDB table that you create there.

        When you establish an Amazon Web Services account, the account has initial quotas on the maximum read capacity units and write capacity units that you can provision across all of your DynamoDB tables in a given Region. Also, there are per-table quotas that apply when you create a table there. For more information, see Service, Account, and Table Quotas page in the Amazon DynamoDB Developer Guide.

        Although you can increase these quotas by filing a case at Amazon Web Services Support Center, obtaining the increase is not instantaneous. The DescribeLimits action lets you write code to compare the capacity you are currently using to those quotas imposed by your account so that you have enough time to apply for an increase before you hit a quota.

        For example, you could use one of the Amazon Web Services SDKs to do the following:

        1. Call DescribeLimits for a particular Region to obtain your current account quotas on provisioned capacity there.

        2. Create a variable to hold the aggregate read capacity units provisioned for all your tables in that Region, and one to hold the aggregate write capacity units. Zero them both.

        3. Call ListTables to obtain a list of all your DynamoDB tables.

        4. For each table name listed by ListTables, do the following:

          • Call DescribeTable with the table name.

          • Use the data returned by DescribeTable to add the read capacity units and write capacity units provisioned for the table itself to your variables.

          • If the table has one or more global secondary indexes (GSIs), loop over these GSIs and add their provisioned capacity values to your variables as well.

        5. Report the account quotas for that Region returned by DescribeLimits, along with the total current provisioned capacity levels you have calculated.

        This will let you see whether you are getting close to your account-level quotas.

        The per-table quotas apply only when you are creating a new table. They restrict the sum of the provisioned capacity of the new table itself and all its global secondary indexes.

        For existing tables and their GSIs, DynamoDB doesn't let you increase provisioned capacity extremely rapidly, but the only quota that applies is that the aggregate provisioned capacity over all your tables and GSIs cannot exceed either of the per-account quotas.

        DescribeLimits should only be called periodically. You can expect throttling errors if you call it more than once in a minute.

        The DescribeLimits Request element has no content.

      • executeStatementAsync

        public Future<ExecuteStatementResult> executeStatementAsync(ExecuteStatementRequest request)
        Description copied from interface: AmazonDynamoDBAsync

        This operation allows you to perform reads and singleton writes on data stored in DynamoDB, using PartiQL.

        For PartiQL reads (SELECT statement), if the total number of processed items exceeds the maximum dataset size limit of 1 MB, the read stops and results are returned to the user as a LastEvaluatedKey value to continue the read in a subsequent operation. If the filter criteria in WHERE clause does not match any data, the read will return an empty result set.

        A single SELECT statement response can return up to the maximum number of items (if using the Limit parameter) or a maximum of 1 MB of data (and then apply any filtering to the results using WHERE clause). If LastEvaluatedKey is present in the response, you need to paginate the result set. If NextToken is present, you need to paginate the result set and include NextToken.

      • getResourcePolicyAsync

        public Future<GetResourcePolicyResult> getResourcePolicyAsync(GetResourcePolicyRequest request)
        Description copied from interface: AmazonDynamoDBAsync

        Returns the resource-based policy document attached to the resource, which can be a table or stream, in JSON format.

        GetResourcePolicy follows an eventually consistent model. The following list describes the outcomes when you issue the GetResourcePolicy request immediately after issuing another request:

        • If you issue a GetResourcePolicy request immediately after a PutResourcePolicy request, DynamoDB might return a PolicyNotFoundException.

        • If you issue a GetResourcePolicyrequest immediately after a DeleteResourcePolicy request, DynamoDB might return the policy that was present before the deletion request.

        • If you issue a GetResourcePolicy request immediately after a CreateTable request, which includes a resource-based policy, DynamoDB might return a ResourceNotFoundException or a PolicyNotFoundException.

        Because GetResourcePolicy uses an eventually consistent query, the metadata for your policy or table might not be available at that moment. Wait for a few seconds, and then retry the GetResourcePolicy request.

        After a GetResourcePolicy request returns a policy created using the PutResourcePolicy request, the policy will be applied in the authorization of requests to the resource. Because this process is eventually consistent, it will take some time to apply the policy to all requests to a resource. Policies that you attach while creating a table using the CreateTable request will always be applied to all requests for that table.

        getResourcePolicyAsync in interface AmazonDynamoDBAsync

      • putItemAsync

        public Future<PutItemResult> putItemAsync(PutItemRequest request)
        Description copied from interface: AmazonDynamoDBAsync

        Creates a new item, or replaces an old item with a new item. If an item that has the same primary key as the new item already exists in the specified table, the new item completely replaces the existing item. You can perform a conditional put operation (add a new item if one with the specified primary key doesn't exist), or replace an existing item if it has certain attribute values. You can return the item's attribute values in the same operation, using the ReturnValues parameter.

        When you add an item, the primary key attributes are the only required attributes.

        Empty String and Binary attribute values are allowed. Attribute values of type String and Binary must have a length greater than zero if the attribute is used as a key attribute for a table or index. Set type attributes cannot be empty.

        Invalid Requests with empty values will be rejected with a ValidationException exception.

        To prevent a new item from replacing an existing item, use a conditional expression that contains the attribute_not_exists function with the name of the attribute being used as the partition key for the table. Since every record must contain that attribute, the attribute_not_exists function will only succeed if no matching item exists.

      • putResourcePolicyAsync

        public Future<PutResourcePolicyResult> putResourcePolicyAsync(PutResourcePolicyRequest request)
        Description copied from interface: AmazonDynamoDBAsync

        Attaches a resource-based policy document to the resource, which can be a table or stream. When you attach a resource-based policy using this API, the policy application is eventually consistent .

        PutResourcePolicy is an idempotent operation; running it multiple times on the same resource using the same policy document will return the same revision ID. If you specify an ExpectedRevisionId that doesn't match the current policy's RevisionId, the PolicyNotFoundException will be returned.

        PutResourcePolicy is an asynchronous operation. If you issue a GetResourcePolicy request immediately after a PutResourcePolicy request, DynamoDB might return your previous policy, if there was one, or return the PolicyNotFoundException. This is because GetResourcePolicy uses an eventually consistent query, and the metadata for your policy or table might not be available at that moment. Wait for a few seconds, and then try the GetResourcePolicy request again.

      • queryAsync

        public Future<QueryResult> queryAsync(QueryRequest request)
        Description copied from interface: AmazonDynamoDBAsync

        You must provide the name of the partition key attribute and a single value for that attribute. Query returns all items with that partition key value. Optionally, you can provide a sort key attribute and use a comparison operator to refine the search results.

        Use the KeyConditionExpression parameter to provide a specific value for the partition key. The Query operation will return all of the items from the table or index with that partition key value. You can optionally narrow the scope of the Query operation by specifying a sort key value and a comparison operator in KeyConditionExpression. To further refine the Query results, you can optionally provide a FilterExpression. A FilterExpression determines which items within the results should be returned to you. All of the other results are discarded.

        A Query operation always returns a result set. If no matching items are found, the result set will be empty. Queries that do not return results consume the minimum number of read capacity units for that type of read operation.

        DynamoDB calculates the number of read capacity units consumed based on item size, not on the amount of data that is returned to an application. The number of capacity units consumed will be the same whether you request all of the attributes (the default behavior) or just some of them (using a projection expression). The number will also be the same whether or not you use a FilterExpression.

        Query results are always sorted by the sort key value. If the data type of the sort key is Number, the results are returned in numeric order; otherwise, the results are returned in order of UTF-8 bytes. By default, the sort order is ascending. To reverse the order, set the ScanIndexForward parameter to false.

        A single Query operation will read up to the maximum number of items set (if using the Limit parameter) or a maximum of 1 MB of data and then apply any filtering to the results using FilterExpression. If LastEvaluatedKey is present in the response, you will need to paginate the result set. For more information, see Paginating the Results in the Amazon DynamoDB Developer Guide.

        FilterExpression is applied after a Query finishes, but before the results are returned. A FilterExpression cannot contain partition key or sort key attributes. You need to specify those attributes in the KeyConditionExpression.

        A Query operation can return an empty result set and a LastEvaluatedKey if all the items read for the page of results are filtered out.

        You can query a table, a local secondary index, or a global secondary index. For a query on a table or on a local secondary index, you can set the ConsistentRead parameter to true and obtain a strongly consistent result. Global secondary indexes support eventually consistent reads only, so do not specify ConsistentRead when querying a global secondary index.

      • scanAsync

        public Future<ScanResult> scanAsync(ScanRequest request)
        Description copied from interface: AmazonDynamoDBAsync

        The Scan operation returns one or more items and item attributes by accessing every item in a table or a secondary index. To have DynamoDB return fewer items, you can provide a FilterExpression operation.

        If the total size of scanned items exceeds the maximum dataset size limit of 1 MB, the scan completes and results are returned to the user. The LastEvaluatedKey value is also returned and the requestor can use the LastEvaluatedKey to continue the scan in a subsequent operation. Each scan response also includes number of items that were scanned (ScannedCount) as part of the request. If using a FilterExpression , a scan result can result in no items meeting the criteria and the Count will result in zero. If you did not use a FilterExpression in the scan request, then Count is the same as ScannedCount.

        Count and ScannedCount only return the count of items specific to a single scan request and, unless the table is less than 1MB, do not represent the total number of items in the table.

        A single Scan operation first reads up to the maximum number of items set (if using the Limit parameter) or a maximum of 1 MB of data and then applies any filtering to the results if a FilterExpression is provided. If LastEvaluatedKey is present in the response, pagination is required to complete the full table scan. For more information, see Paginating the Results in the Amazon DynamoDB Developer Guide.

        Scan operations proceed sequentially; however, for faster performance on a large table or secondary index, applications can request a parallel Scan operation by providing the Segment and TotalSegments parameters. For more information, see Parallel Scan in the Amazon DynamoDB Developer Guide.

        By default, a Scan uses eventually consistent reads when accessing the items in a table. Therefore, the results from an eventually consistent Scan may not include the latest item changes at the time the scan iterates through each item in the table. If you require a strongly consistent read of each item as the scan iterates through the items in the table, you can set the ConsistentRead parameter to true. Strong consistency only relates to the consistency of the read at the item level.

        DynamoDB does not provide snapshot isolation for a scan operation when the ConsistentRead parameter is set to true. Thus, a DynamoDB scan operation does not guarantee that all reads in a scan see a consistent snapshot of the table when the scan operation was requested.

      • scanAsync

        public Future<ScanResult> scanAsync(ScanRequest request,
 AsyncHandler<ScanRequest,ScanResult> asyncHandler)
        Description copied from interface: AmazonDynamoDBAsync

        The Scan operation returns one or more items and item attributes by accessing every item in a table or a secondary index. To have DynamoDB return fewer items, you can provide a FilterExpression operation.

        If the total size of scanned items exceeds the maximum dataset size limit of 1 MB, the scan completes and results are returned to the user. The LastEvaluatedKey value is also returned and the requestor can use the LastEvaluatedKey to continue the scan in a subsequent operation. Each scan response also includes number of items that were scanned (ScannedCount) as part of the request. If using a FilterExpression , a scan result can result in no items meeting the criteria and the Count will result in zero. If you did not use a FilterExpression in the scan request, then Count is the same as ScannedCount.

        Count and ScannedCount only return the count of items specific to a single scan request and, unless the table is less than 1MB, do not represent the total number of items in the table.

        A single Scan operation first reads up to the maximum number of items set (if using the Limit parameter) or a maximum of 1 MB of data and then applies any filtering to the results if a FilterExpression is provided.

        public Future<TransactGetItemsResult> transactGetItemsAsync(TransactGetItemsRequest request)
        Description copied from interface: AmazonDynamoDBAsync

        TransactGetItems is a synchronous operation that atomically retrieves multiple items from one or more tables (but not from indexes) in a single account and Region. A TransactGetItems call can contain up to 100 TransactGetItem objects, each of which contains a Get structure that specifies an item to retrieve from a table in the account and Region. A call to TransactGetItems cannot retrieve items from tables in more than one Amazon Web Services account or Region. The aggregate size of the items in the transaction cannot exceed 4 MB.

        DynamoDB rejects the entire TransactGetItems request if any of the following is true:

        • A conflicting operation is in the process of updating an item to be read.

        • There is insufficient provisioned capacity for the transaction to be completed.

      • transactWriteItemsAsync

        public Future<TransactWriteItemsResult> transactWriteItemsAsync(TransactWriteItemsRequest request)
        Description copied from interface: AmazonDynamoDBAsync

        TransactWriteItems is a synchronous write operation that groups up to 100 action requests. These actions can target items in different tables, but not in different Amazon Web Services accounts or Regions, and no two actions can target the same item. For example, you cannot both ConditionCheck and Update the same item. The aggregate size of the items in the transaction cannot exceed 4 MB.

        The actions are completed atomically so that either all of them succeed, or all of them fail. They are defined by the following objects:

        • Put — Initiates a PutItem operation to write a new item. This structure specifies the primary key of the item to be written, the name of the table to write it in, an optional condition expression that must be satisfied for the write to succeed, a list of the item's attributes, and a field indicating whether to retrieve the item's attributes if the condition is not met.

        • Update — Initiates an UpdateItem operation to update an existing item. This structure specifies the primary key of the item to be updated, the name of the table where it resides, an optional condition expression that must be satisfied for the update to succeed, an expression that defines one or more attributes to be updated, and a field indicating whether to retrieve the item's attributes if the condition is not met.

        • Delete — Initiates a DeleteItem operation to delete an existing item. This structure specifies the primary key of the item to be deleted, the name of the table where it resides, an optional condition expression that must be satisfied for the deletion to succeed, and a field indicating whether to retrieve the item's attributes if the condition is not met.

        • ConditionCheck — Applies a condition to an item that is not being modified by the transaction. This structure specifies the primary key of the item to be checked, the name of the table where it resides, a condition expression that must be satisfied for the transaction to succeed, and a field indicating whether to retrieve the item's attributes if the condition is not met.

        DynamoDB rejects the entire TransactWriteItems request if any of the following is true:

        • A condition in one of the condition expressions is not met.

        • An ongoing operation is in the process of updating the same item.

        • There is insufficient provisioned capacity for the transaction to be completed.

        • An item size becomes too large (bigger than 400 KB), a local secondary index (LSI) becomes too large, or a similar validation error occurs because of changes made by the transaction.

        Adds or removes replicas in the specified global table. The global table must already exist to be able to use this operation. Any replica to be added must be empty, have the same name as the global table, have the same key schema, have DynamoDB Streams enabled, and have the same provisioned and maximum write capacity units.

        This documentation is for version 2017年11月29日 (Legacy) of global tables, which should be avoided for new global tables. Customers should use Global Tables version 2019年11月21日 (Current) when possible, because it provides greater flexibility, higher efficiency, and consumes less write capacity than 2017年11月29日 (Legacy).

        To determine which version you're using, see Determining the global table version you are using. To update existing global tables from version 2017年11月29日 (Legacy) to version 2019年11月21日 (Current), see Upgrading global tables.

        For global tables, this operation only applies to global tables using Version 2019年11月21日 (Current version). If you are using global tables Version 2019年11月21日 you can use UpdateTable instead.

        Although you can use UpdateGlobalTable to add replicas and remove replicas in a single request, for simplicity we recommend that you issue separate requests for adding or removing replicas.

        If global secondary indexes are specified, then the following conditions must also be met:

        • The global secondary indexes must have the same name.

        Description copied from interface: AmazonDynamoDBAsync

        Modifies the provisioned throughput settings, global secondary indexes, or DynamoDB Streams settings for a given table.

        For global tables, this operation only applies to global tables using Version 2019年11月21日 (Current version).

        You can only perform one of the following operations at once:

        • Modify the provisioned throughput settings of the table.

        • Remove a global secondary index from the table.

        • Create a new global secondary index on the table. After the index begins backfilling, you can use UpdateTable to perform other operations.

        UpdateTable is an asynchronous operation; while it's executing, the table status changes from ACTIVE to UPDATING. While it's UPDATING, you can't issue another UpdateTable request. When the table returns to the ACTIVE state, the UpdateTable operation is complete.

        • Modify the provisioned throughput settings of the table.

        • Remove a global secondary index from the table.

        • Create a new global secondary index on the table. After the index begins backfilling, you can use UpdateTable to perform other operations.

        UpdateTable is an asynchronous operation; while it's executing, the table status changes from ACTIVE to UPDATING. While it's UPDATING, you can't issue another UpdateTable request. When the table returns to the ACTIVE state, the UpdateTable operation is complete.

        Specified by:
        updateTableAsync in interface AmazonDynamoDBAsync
        Parameters:
        request - Represents the input of an UpdateTable operation.
        asyncHandler - Asynchronous callback handler for events in the lifecycle of the request. Users can provide an implementation of the callback methods in this interface to receive notification of successful or unsuccessful completion of the operation.
        Returns:
        A Java Future containing the result of the UpdateTable operation returned by the service.

      • updateTimeToLiveAsync

        public Future<UpdateTimeToLiveResult> updateTimeToLiveAsync(UpdateTimeToLiveRequest request)
        Description copied from interface: AmazonDynamoDBAsync

        The UpdateTimeToLive method enables or disables Time to Live (TTL) for the specified table. A successful UpdateTimeToLive call returns the current TimeToLiveSpecification. It can take up to one hour for the change to fully process. Any additional UpdateTimeToLive calls for the same table during this one hour duration result in a ValidationException.

        TTL compares the current time in epoch time format to the time stored in the TTL attribute of an item. If the epoch time value stored in the attribute is less than the current time, the item is marked as expired and subsequently deleted.

        The epoch time format is the number of seconds elapsed since 12:00:00 AM January 1, 1970 UTC.

        DynamoDB deletes expired items on a best-effort basis to ensure availability of throughput for other data operations.

        DynamoDB typically deletes expired items within two days of expiration. The exact duration within which an item gets deleted after expiration is specific to the nature of the workload. Items that have expired and not been deleted will still show up in reads, queries, and scans.

        As items are deleted, they are removed from any local secondary index and global secondary index immediately in the same eventually consistent way as a standard delete operation.

        For more information, see Time To Live in the Amazon DynamoDB Developer Guide.
