Enclosing class:

FirestoreV1

public static final class FirestoreV1.BatchWriteWithDeadLetterQueue
extends org.apache.beam.sdk.transforms.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.
