A global cache is a repository for data that you want to reuse. You can use the new global cache facility in Message Broker to store correlation information for use beyond a specific node, instance of a message flow, execution group, or broker. The Message Broker global cache facilitates sharing of data across processes (both in the same broker, and across brokers) and eliminates the need for an alternative solution, such as a database. You can use one node to store data in the global cache, then a second node (in the same message flow or a separate flow), can retrieve that data from the global cache.
This session will explore the aspects of data caching and sharing within your message flows using the WebSphere eXtreme Scale technologies and the Message Broker global cache. It will also look at the benefits of the global cache functionality in comparison with other solutions such as databases and also take a look at how to access an eXtreme Scale cache held outside of Message Broker.
