public sealed class ChangeStreamConfig : IMessage<ChangeStreamConfig>, IEquatable<ChangeStreamConfig>, IDeepCloneable<ChangeStreamConfig>, IBufferMessage, IMessage
Reference documentation and code samples for the Google Cloud Bigtable Administration v2 API class ChangeStreamConfig.
How long the change stream should be retained. Change stream data older
than the retention period will not be returned when reading the change
stream from the table.
Values must be at least 1 day and at most 7 days, and will be truncated to
microsecond granularity.
