public class StorageApiWriteRecordsInconsistent<DestinationT,ElementT>
extends PTransform<PCollection<KV<DestinationT,StorageApiWritePayload>>,PCollectionTuple>

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.

Method Detail

expand

public PCollectionTuple expand(PCollection<KV<DestinationT,StorageApiWritePayload>> input)

Description copied from class: PTransform

Override this method to specify how this PTransform should be expanded on the given InputT.

NOTE: This method should not be called directly. Instead apply the PTransform should be applied to the InputT using the apply method.

Composite transforms, which are defined in terms of other transforms, should return the output of one of the composed transforms. Non-composite transforms, which do not apply any transforms internally, should return a new unbound output and register evaluators (via backend-specific registration methods).
