java.lang.Object

org.apache.beam.sdk.transforms.PTransform<InT,OutT>

org.apache.beam.sdk.io.gcp.firestore.FirestoreV1.BatchWriteWithDeadLetterQueue

All Implemented Interfaces:

java.io.Serializable, HasDisplayData

Enclosing class:

FirestoreV1

public static final class FirestoreV1.BatchWriteWithDeadLetterQueue
extends PTransform<InT,OutT>

Concrete class representing a PTransform<PCollection<Write>, PCollection<FirestoreV1.WriteFailure> which will write to Firestore. FirestoreV1.WriteFailures output by this PTransform are those writes which were not able to be applied to Cloud Firestore.

Use this BatchWrite when you do not want a failed write to error an entire bundle.

This class is part of the Firestore Connector DSL, it has a type safe builder accessible via FirestoreIO.v1().write().batchWrite().withDeadLetterQueue().

All request quality-of-service for an instance of this PTransform is scoped to the worker and configured via FirestoreV1.Transform.Builder.withRpcQosOptions(RpcQosOptions).

Writes performed against Firestore will be ordered and grouped to maximize throughput while maintaining a high request success rate. Batch sizes will be determined by the QOS layer.

Method Detail

expand

public PCollection<FirestoreV1.WriteFailure> expand(PCollection<com.google.firestore.v1.Write> 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).

Specified by:

expand in class PTransform<PCollection<com.google.firestore.v1.Write>,PCollection<FirestoreV1.WriteFailure>>

toBuilder

public FirestoreV1.BatchWriteWithDeadLetterQueue.Builder toBuilder()

Create a new Builder from the current instance.

Returns:

a new instance of a Builder initialized to the current state of this instance
