Package io.camunda.zeebe.transport.stream.impl

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.

All Implemented Interfaces:

ImmutableStreamRegistry<M>

public class RemoteStreamRegistry<M>
extends Object
implements ImmutableStreamRegistry<M>

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.

Method Details

add

public void add(org.agrona.concurrent.UnsafeBuffer streamType,
 UUID streamId,
 MemberId receiver,
 M properties)

Adds a stream receiver that can receive data from the stream with the given streamType.

Parameters:

streamType - type of the stream

streamId - id of the stream. The pair (receiver, streamId) must uniquely identify the stream.

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

properties - properties used by the producer to generate data to be pushed to the stream

remove

public void remove(UUID streamId,
 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<ImmutableStreamRegistry.StreamConsumer<M>> get(org.agrona.concurrent.UnsafeBuffer streamType)

Description copied from interface: ImmutableStreamRegistry

Returns a set of streams for the given type.

Implementations of this must be thread-safe.

Specified by:

get in interface ImmutableStreamRegistry<M>

Parameters:

streamType - type of the stream

Returns:

set of streams for the given type

clear

public void clear()
