  • CLEANUP_POLICY_COMPACT_AND_DELETE: this policy use both compaction and deletion for messages and log segments.
    compression_type enum CompressionType
    The compression type for a given topic.
    • COMPRESSION_TYPE_UNCOMPRESSED: no codec (uncompressed).
    • COMPRESSION_TYPE_ZSTD: Zstandard codec.
    • COMPRESSION_TYPE_LZ4: LZ4 codec.

                                                  created_by string
                                                  ID of the user or service account who initiated the operation.
                                                  modified_at google.protobuf.Timestamp
                                                  The time when the Operation resource was last modified.
                                                  done bool
                                                  If the value is false, it means the operation is still in progress. If true, the operation is completed, and either error or response is available.
                                                  metadata google.protobuf.Any<DeleteTopicMetadata>
                                                  Service-specific metadata associated with the operation. It typically contains the ID of the target resource that the operation is performed on. Any method that returns a long-running operation should document the metadata type, if any.
                                                  result oneof: error or response
                                                  The operation result. If done == false and there was no failure detected, neither error nor response is set. If done == false and there was a failure detected, error is set. If done == true, exactly one of error or response is set.
                                                    error google.rpc.Status
                                                  The error result of the operation in case of failure or cancellation.
                                                    response google.protobuf.Any<google.protobuf.Empty>
                                                  if operation finished successfully.
