Specified by:

initSink in class AbstractGrpcSink

publish

public void publish(Object payload,
                    io.siddhi.core.util.transport.DynamicOptions dynamicOptions,
                    io.siddhi.core.util.snapshot.state.State state)
             throws io.siddhi.core.exception.ConnectionUnavailableException

Specified by:

publish in class io.siddhi.core.stream.output.sink.Sink

Throws:

connect

public void connect()
             throws io.siddhi.core.exception.ConnectionUnavailableException

This method will be called before the processing method. Intention to establish connection to publish event.

Specified by:

connect in class io.siddhi.core.stream.output.sink.Sink

Throws:
