Description
The following code always returns single object, even if WAL TAIL API (https://docs.arangodb.com/3.12/develop/http-api/replication/write-ahead-log/#tail-recent-server-operations) returns multiple json objects:
protected CompletableFuture<Response<OperationResponse[]>> fetchEventsFromCurrentTick(ArangoClientProvider sourceProvider, ProcessingState processingState) { Request<OperationResponse[]> tailRequest = Request.<OperationResponse[]>builder().path(WAL_TAIL_PATH.formatted(sourceProvider.arangoDBName())) .method(Request.Method.GET) .queryParam("syncerId", processorSettings.walSyncerId) .queryParam("chunkSize", String.valueOf(processorSettings.chunkSize)) .queryParam("lastScanned", String.valueOf(processingState.getLastScannedTick())) .queryParam("from", String.valueOf(processingState.getCurrentTick())) .build(); return sourceProvider.getClient().execute(tailRequest, OperationResponse[].class); }
As far as I investigated it, it's caused by Jackson behaviour which only allows for properly defined json objects. Unfortunately, json objects are not wrapped in array in Arango API.
I tried using RawJson type - it doesn't matter.
