Justin, With our current infrastructure, we have found that using one broker will not satisfy our throughput requirements even with various tuning. We have been using the ActiveMQ Classic Performance Module plugin to test against Artemis:
https://activemq.apache.org/components/classic/documentation/activemq-classic-performance-module-users-manual We would like to setup an active-active symmetric cluster where all brokers are active primaries similar to what this diagram shows in Figure 16.2: https://docs.redhat.com/en/documentation/red_hat_amq/7.4/html/configuring_amq_broker/setting-up-broker-cluster-configuring#common-broker-cluster-topologies-configuring Regards, William Crowell From: Justin Bertram <jbert...@apache.org> Date: Wednesday, March 19, 2025 at 9:37 AM To: users@activemq.apache.org <users@activemq.apache.org> Subject: Re: What HA Replication Policy Is For Active-Active Topology I lost the plot somewhere along the way I think. What specifically is your use-case? Why are you wanting multiple clusters?
