Package io.siddhi.core.util.transport

Class MultiClientDistributedSink

java.lang.Object

io.siddhi.core.stream.output.sink.Sink

io.siddhi.core.stream.output.sink.distributed.DistributedTransport

io.siddhi.core.util.transport.MultiClientDistributedSink

All Implemented Interfaces:

SinkListener

public class MultiClientDistributedSink
extends DistributedTransport

This is the distributed transport to publish to multiple endpoints using client/publisher for each endpoint. There will be a separate independent Sink instance connecting to each destination. This class interacts with Sink interface and it does not make any assumptions on the underlying transport implementation.
