A-MQ 7 consists of several new components and features, it is base on Project Apache ActiveMQ Artemis. The code base was donated by HornetQ. Having high performance journal base on NIO implementation, allows A-MQ 7 to become a fast , high performance and reliable messaging platform. Rather than relying other persistence storage it is very highly optimized for general message use cases. The message broker as always allows you to balance load across a cluster of brokers, the balancing of the message not only distributed the incoming message to brokers sequentially but also takes into the account of the number of consumers and selectors in the broker so the performance can achieved even distribution of the load.
One of the bigger innovation of A-MQ 7 is the introduction of Interconnects, Interconnect is a message router you can use to build large-scale messaging networks. A-MQ Interconnect uses the AMQP protocol to create a redundant application-level messaging network. It works as an interconnect layer between messaging clients and their brokers. And why do we need it? The beauty of the interconnect allows you to solve the good old problems when we only have multiple brokers, there could be too many clients trying to connect to to a single point of brokers, one broker could have too many queues create, one of a broker handling too much throughput comparing with the others, have interconnect is to add another routing layer before your broker, it is flexible nature allows messages to flow through it and evenly spread the load. It automatically find the fasting routing path so the message will arrive efficiently. And since it's base on AMQP protocols, you can set your own selector on it base on your messaging routing logic.
And as always, we still have Hawtio as the management tooling, where you can see the details of how the brokers are doing now.
For those of you who uses the old version of A-MQ or HornetQ, A-MQ 7 support both A-MQ 6.x and HornetQ clients for backward compatibility.
