Enum StreamingMode

java.lang.Object
java.lang.Enum<StreamingMode>
com.google.dataflow.v1beta3.StreamingMode
All Implemented Interfaces:
com.google.protobuf.Internal.EnumLite, com.google.protobuf.ProtocolMessageEnum, Serializable, Comparable<StreamingMode>
@Generated public enum StreamingMode extends Enum<StreamingMode> implements com.google.protobuf.ProtocolMessageEnum
 Specifies the Streaming Engine message processing guarantees. Reduces cost
 and latency but might result in duplicate messages written to storage.
 Designed to run simple mapping streaming ETL jobs at the lowest cost.
 For example, Change Data Capture (CDC) to BigQuery is a canonical use
 case. For more information, see
 [Set the pipeline streaming
 mode](https://cloud.google.com/dataflow/docs/guides/streaming-modes).
Protobuf enum google.dataflow.v1beta3.StreamingMode

  • Enum Constant Details

    • STREAMING_MODE_UNSPECIFIED

      public static final StreamingMode STREAMING_MODE_UNSPECIFIED
       Run in the default mode.
      STREAMING_MODE_UNSPECIFIED = 0;

    • STREAMING_MODE_EXACTLY_ONCE

      public static final StreamingMode STREAMING_MODE_EXACTLY_ONCE
       In this mode, message deduplication is performed against persistent state
 to make sure each message is processed and committed to storage exactly
 once.
      STREAMING_MODE_EXACTLY_ONCE = 1;

    • STREAMING_MODE_AT_LEAST_ONCE

      public static final StreamingMode STREAMING_MODE_AT_LEAST_ONCE
       Message deduplication is not performed. Messages might be processed
 multiple times, and the results are applied multiple times.
 Note: Setting this value also enables Streaming Engine and
 Streaming Engine resource-based billing.
      STREAMING_MODE_AT_LEAST_ONCE = 2;

    • UNRECOGNIZED

      public static final StreamingMode UNRECOGNIZED

  • Field Details

    • STREAMING_MODE_UNSPECIFIED_VALUE

      public static final int STREAMING_MODE_UNSPECIFIED_VALUE
       Run in the default mode.

    • STREAMING_MODE_EXACTLY_ONCE_VALUE

      public static final int STREAMING_MODE_EXACTLY_ONCE_VALUE
