Class RemoteStreamRegistry<M>

java.lang.Object

io.camunda.zeebe.transport.stream.impl.RemoteStreamRegistry<M>

Type Parameters:

M - the type of the properties of the stream.

public class RemoteStreamRegistry<M>
extends Object

A registry for remote streams. The streams are typically between broker and the gateway, where the broker pushes data to the stream and the gateway consumes them.

A stream is uniquely identified by the streamId and the receiver. A stream has also an associated type and properties. Two streams with the same type and properties can consume the same data.

 MemberId receiver)

Removes the stream.

Parameters:

streamId - id of the stream

receiver - The id of the node that receives data from the stream

removeAll

public void removeAll(MemberId receiver)

Removes all stream from the given receiver

Parameters:

receiver - id of the node

get

public Set<io.camunda.zeebe.transport.stream.impl.AggregatedRemoteStream<M>> get(org.agrona.concurrent.UnsafeBuffer streamType)

clear

public void clear()
