public sealed class BigQueryDestinationConfig : IMessage<BigQueryDestinationConfig>, IEquatable<BigQueryDestinationConfig>, IDeepCloneable<BigQueryDestinationConfig>, IBufferMessage, IMessage
Reference documentation and code samples for the DataStream v1 API class BigQueryDestinationConfig.
The guaranteed data freshness (in seconds) when querying tables created by
the stream. Editing this field will only affect new tables created in the
future, but existing tables will not be impacted. Lower values mean that
queries will return fresher data, but may result in higher cost.
