All Implemented Interfaces:

java.io.Serializable, org.apache.flink.api.common.functions.Function, org.apache.flink.api.common.functions.RichFunction, org.apache.flink.streaming.api.functions.source.ParallelSourceFunction<org.apache.beam.sdk.util.WindowedValue<byte[]>>, org.apache.flink.streaming.api.functions.source.SourceFunction<org.apache.beam.sdk.util.WindowedValue<byte[]>>

Deprecated.

Legacy non-portable source which can be replaced by a DoFn with timers. https://jira.apache.org/jira/browse/BEAM-8353

@Deprecated
public class StreamingImpulseSource
extends org.apache.flink.streaming.api.functions.source.RichParallelSourceFunction<org.apache.beam.sdk.util.WindowedValue<byte[]>>

A streaming source that periodically produces a byte array. This is mostly useful for debugging, or for triggering periodic behavior in a portable pipeline.
