All Implemented Interfaces:

java.io.Serializable, org.apache.beam.sdk.transforms.display.HasDisplayData

public class StorageApiWriteUnshardedRecords<DestinationT,ElementT>
extends org.apache.beam.sdk.transforms.PTransform<org.apache.beam.sdk.values.PCollection<org.apache.beam.sdk.values.KV<DestinationT,StorageApiWritePayload>>,org.apache.beam.sdk.values.PCollectionTuple>

Write records to the Storage API using a standard batch approach. PENDING streams are used, which do not become visible until they are finalized and committed. Each input bundle to the DoFn creates a stream per output table, appends all records in the bundle to the stream, and schedules a finalize/commit operation at the end.
