All Implemented Interfaces:

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

public class StorageApiWriteRecordsInconsistent<DestinationT,ElementT>
extends org.apache.beam.sdk.transforms.PTransform<org.apache.beam.sdk.values.PCollection<org.apache.beam.sdk.values.KV<DestinationT,byte[]>>,org.apache.beam.sdk.values.PCollection<java.lang.Void>>

A transform to write sharded records to BigQuery using the Storage API. This transform uses the default stream to write the records. Records written will show up in BigQuery immediately, however exactly once is not guaranteed - duplicates may appear in the output. For exactly-once writes, use StorageApiWritesShardedRecords or StorageApiWriteUnshardedRecords.
