Chapter 4. Technology preview
This section describes Technology Preview features in AMQ Broker 7.9.
Technology Preview features are not supported with Red Hat production service-level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them for production. For more information, see Red Hat Technology Preview Features Support Scope.
- Quorum voting improvements
- In previous versions of AMQ Broker you needed to configure at least three live-backup pairs to use quorum voting to avoid having two live brokers when using replication high availability (HA) policy. Starting in 7.9, you can configure failover to use Apache Curator and Apache ZooKeeper to provide quorum voting using two brokers. For information about using this feature, see High Availability and Failover in the Apache ActiveMQ Artemis documentation.
- Client connection balancing improvements
-
In previous releases, there was no method to balance client connections server-side. Starting in 7.9, you can specify pools of brokers and policies for balancing client connections. For example, you can specify a
LEAST_CONNECTIONSpolicy that ensures that clients are redirected to brokers with the fewest active connections. For information about using this feature, see Broker Balancers in the Apache ActiveMQ Artemis documentation. - Viewing brokers in Fuse Console
You can configure an Operator-based broker deployment to use Fuse Console for OpenShift instead of AMQ Management Console. When you have configured your broker deployment appropriately, Fuse Console discovers the brokers and displays them on a dedicated
Artemistab. For more information, see Viewing brokers in Fuse Console in Deploying AMQ Broker on OpenShift.NoteViewing brokers in Fuse Console is a Technology Preview feature for Fuse 7.8.
