New & Noteworthy

  • [Driver] Support for IPC media was added to response channels. (#1761)

    The feature works exactly the same as for UDP media but does not require control endpoint to be specified.

    For an example see
    ResponseChannelsTest#shouldConnectResponsePublicationUsingImageAndIpc.

  • [Driver] Add support for response-correlation-id=prototype to allow pre-creating response publications to
    reserve and hold onto a local port. (#1863)

    For usage example see ResponseChannelsTest.

  • [Driver] Add API to create counters asynchronously.

    Counters can now be created asynchronously using Aeron.asyncAddCounter and Aeron.asyncAddStaticCounter methods.
    Created counter is returned by the Aeron.getCounter method. There is also Aeron.asyncRemoveCounter to asynchronously
    remove counter by registrationId.

    For usage example see
    CounterTest#shouldAddCounterAsynchronously,
    CounterTest#shouldAddCounterAsynchronouslyUsingLabelAndTypeId
    and
    CounterTest#shouldAddStaticCounterAsynchronously.

  • [Archive] Named Archive clients.

    Client name can be specified using AeronArchive.Context.clientName(java.lang.String) API or
    aeron.archive.client.name system property. Once specified the name will be sent to the Archive with connect request
    along with additional information such as client version. Archive will add a new control-session counter
    (typeId=113) for each connected client:

    control-session: name=test client 5 version=1.49.0-SNAPSHOT commit=e79ebfa4ff sourceIdentity=127.0.0.1:51360 sessionId=1083930759 - archiveId=519

  • [Cluster] Named Cluster clients.

    Client name can be specified using AeronCluster.Context.clientName(java.lang.String) API or
    aeron.cluster.client.name system property. Once specified the name will be sent to the Cluster with connect request
    along with additional information such as client version. Cluster will add a new cluster-session counter
    (typeId=241) for each connected client:

    cluster-session: name=test client version=1.49.0-SNAPSHOT commit=4ac30af55a sourceIdentity=127.0.0.1:54444 sessionId=325223904 - clusterId=0

  • [Cluster] Default Authorisation Service

    Updated the default AuthorisationService to allow heartbeat and standby-snapshot requests, which are required for Aeron Cluster Standby.

  • [Breaking] org.agrona.concurrent.ShutdownSignalBarrier changes in Agrona 2.3.0.
    Please read the corresponding release notes on how to upgrade.

  • [Breaking] ClusteredServiceContainer.Context.shutdownSignalBarrier, ConsensusModule.Context.shutdownSignalBarrier
    and ClusterBackup.Context.shutdownSignalBarrier methods were removed and replaced with an explicit ShutdownSignalBarrier.

    For example this is how ConsensusModule#main changed:

    • Before:

      public static void main(final String[] args)
{
    loadPropertiesFiles(args);

    try (ConsensusModule consensusModule = launch())
    {
        consensusModule.context().shutdownSignalBarrier().await();
        System.out.println("Shutdown ConsensusModule...");
    }
}

    • After:

      public static void main(final String[] args)
{
    loadPropertiesFiles(args);

    try (ShutdownSignalBarrier barrier = new ShutdownSignalBarrier();
        ConsensusModule ignored = launch(new Context().terminationHook(barrier::signalAll)))
    {
        barrier.await();
        System.out.println("Shutdown ConsensusModule...");
    }
}

  • [Breaking] Aeron jars no longer provide OSGI metadata as bnd plugin was removed, because it breaks
    compatibility with Gradle 9.1 and causes self-dependency via baseline task.

  • [Archive] Return an error code when replaying and stopping an empty recording. (#1854)
  • [Archive] Capture abort reason in RecordingSession.
  • [Archive] Add additional "length" that will replay the data available, but not follow a live recording. Add more
