Class RemoteStreamerImpl<M,P extends BufferWriter>

java.lang.Object

io.camunda.zeebe.scheduler.Actor

io.camunda.zeebe.transport.stream.impl.RemoteStreamerImpl<M,P>

All Implemented Interfaces:

AsyncClosable, ConcurrencyControl, RemoteStreamer<M,P>, AutoCloseable, Executor

public final class RemoteStreamerImpl<M,P extends BufferWriter>
extends Actor
implements RemoteStreamer<M,P>

RemoteStreamImpl is an actor, and any payload pushed will be pushed asynchronously.

NOTE: any payload pushed is sent via the stream from RemoteStreamer.streamFor(DirectBuffer) will be asynchronous, so the payload should be immutable, and the errors reported to the given RemoteStreamErrorHandler may be reported on different threads.

Method Details

streamFor

public Optional<RemoteStream<M,P>> streamFor(org.agrona.DirectBuffer streamType,
 Predicate<M> filter)

Description copied from interface: RemoteStreamer

Returns a valid stream for the given streamType, or Optional.empty() if there is none.

The predicate should return false to exclude streams from the list of possible streams.

Specified by:

streamFor in interface RemoteStreamer<M,P extends BufferWriter>

Parameters:

streamType - the job type to look for

filter - a filter to include/exclude eligible job streams based on their properties

Returns:

a job stream which matches the type and given filter, or Optional.empty() if none match
