A message indicating that the client should stop reading from the stream. If status is OK and continuation_tokens & new_partitions are empty, the stream has finished (for example if there was an end_time specified). If continuation_tokens & new_partitions are present, then a change in partitioning requires the client to open a new stream for each token to resume reading. Example: [B, D) ends | v new_partitions: [A, C) [C, E) continuation_tokens.partitions: [B,C) [C,D) ^---^ ^---^ ^ ^ | | | StreamContinuationToken 2 | StreamContinuationToken 1 To read the new partition [A,C), supply the continuation tokens whose ranges cover the new partition, for example ContinuationToken[A,B) & ContinuationToken[B,C).

Value parameters

continuationTokens: If non-empty, contains the information needed to resume reading their associated partitions.
newPartitions: If non-empty, contains the new partitions to start reading from, which are related to but not necessarily identical to the partitions for the above continuation_tokens.
status: The status of the stream.

Self type: CloseStream.type

A message corresponding to one or more mutations to the partition being streamed. A single logical DataChange message may also be split across a sequence of multiple individual messages. Messages other than the first in a sequence will only have the type and chunks fields populated, with the final message in the sequence also containing done set to true.

Value parameters

chunks: The mutations associated with this change to the partition. May contain complete mutations or chunks of a multi-message chunked DataChange record.
commitTimestamp: The timestamp at which the mutation was applied on the Bigtable server.
done: When true, indicates that the entire DataChange has been read and the client can safely process the message.
estimatedLowWatermark: An estimate of the commit timestamp that is usually lower than or equal to any timestamp for a record that will be delivered in the future on the stream. It is possible that, under particular circumstances that a future record has a timestamp is is lower than a previously seen timestamp. For an example usage see https://beam.apache.org/documentation/basics/#watermarks
rowKey: The row key for all mutations that are part of this DataChange. If the DataChange is chunked across multiple messages, then this field will only be set for the first message.
sourceClusterId: The cluster where the mutation was applied. Not set when type is GARBAGE_COLLECTION.
tiebreaker: A value that lets stream consumers reconstruct Bigtable's conflict resolution semantics. https://cloud.google.com/bigtable/docs/writes#conflict-resolution In the event that the same row key, column family, column qualifier, timestamp are modified on different clusters at the same commit_timestamp, the mutation with the larger tiebreaker will be the one chosen for the eventually consistent state of the system.
token: An encoded position for this stream's partition to restart reading from. This token is for the StreamPartition from the request.
type: The type of the mutation.

Self type: DataChange.type

A periodic message with information that can be used to checkpoint the state of a stream.

Value parameters

continuationToken: A token that can be provided to a subsequent ReadChangeStream call to pick up reading at the current stream position.
estimatedLowWatermark: An estimate of the commit timestamp that is usually lower than or equal to any timestamp for a record that will be delivered in the future on the stream. It is possible that, under particular circumstances that a future record has a timestamp is is lower than a previously seen timestamp.

A partial or complete mutation.

Value parameters

chunkInfo: If set, then the mutation is a SetCell with a chunked value across multiple messages.
mutation: If this is a continuation of a chunked message (chunked_value_offset > 0), ignore all fields except the SetCell's value and merge it with the previous message by concatenating the value fields.

Returns the Java descriptors for this message. It is recommended to use scalaDescriptors. The Java descriptors are available even when Java conversions is disabled, however they are not available in Scala.js or scala-native.
