Bigtable Data Client Async

class google.cloud.bigtable.data._async.client.BigtableDataClientAsync(*, project: str | None = None, pool_size: int = 3, credentials: google.auth.credentials.Credentials | None = None, client_options: dict[str, Any] | 'google.api_core.client_options.ClientOptions' | None = None)

Bases: google.cloud.client.ClientWithProject

Create a client instance for the Bigtable Data API

Client should be created within an async context (running event loop)

• Parameters

  • project – the project which the client acts on behalf of. If not passed, falls back to the default inferred from the environment.

  • pool_size – The number of grpc channels to maintain in the internal channel pool.

  • credentials – Thehe OAuth2 Credentials to use for this client. If not passed (and if no _http object is passed), falls back to the default inferred from the environment.

  • client_options – Client options used to set user options on the client. API Endpoint should be set through client_options.

• Raises

  • RuntimeError – if called outside of an async context (no running event loop)

  • ValueError – if pool_size is less than 1

async close(timeout: float = 2.0)

Cancel all background tasks

get_table(instance_id: str, table_id: str, *args, **kwargs)

Returns a table instance for making data API requests. All arguments are passed directly to the TableAsync constructor.

• Parameters

  • instance_id – The Bigtable instance ID to associate with this client. instance_id is combined with the client’s project to fully specify the instance

  • table_id – The ID of the table. table_id is combined with the instance_id and the client’s project to fully specify the table

  • app_profile_id – The app profile to associate with requests. https://cloud.google.com/bigtable/docs/app-profiles

  • default_read_rows_operation_timeout – The default timeout for read rows operations, in seconds. If not set, defaults to 600 seconds (10 minutes)

  • default_read_rows_attempt_timeout – The default timeout for individual read rows rpc requests, in seconds. If not set, defaults to 20 seconds

  • default_mutate_rows_operation_timeout – The default timeout for mutate rows operations, in seconds. If not set, defaults to 600 seconds (10 minutes)

  • default_mutate_rows_attempt_timeout – The default timeout for individual mutate rows rpc requests, in seconds. If not set, defaults to 60 seconds

  • default_operation_timeout – The default timeout for all other operations, in seconds. If not set, defaults to 60 seconds

  • default_attempt_timeout – The default timeout for all other individual rpc requests, in seconds. If not set, defaults to 20 seconds

  • default_read_rows_retryable_errors – a list of errors that will be retried if encountered during read_rows and related operations. Defaults to 4 (DeadlineExceeded), 14 (ServiceUnavailable), and 10 (Aborted)

  • default_mutate_rows_retryable_errors – a list of errors that will be retried if encountered during mutate_rows and related operations. Defaults to 4 (DeadlineExceeded) and 14 (ServiceUnavailable)

  • default_retryable_errors – a list of errors that will be retried if encountered during all other operations. Defaults to 4 (DeadlineExceeded) and 14 (ServiceUnavailable)

• Returns

  a table instance for making data API requests

• Return type

  TableAsync

• Raises

  RuntimeError – if called outside of an async context (no running event loop)
