What's new in this release
WSO2 Message Broker version 2.1.0 is the successor of version 2.0.1. It is based on the Carbon platform version 4.1.4. It contains the following new features and enhancements:
- The new support for hierarchical topics allows you to subscribe to one or more topics based on their location in a hierarchy, such as subscribing to all child topics under a parent topic.
- If you need to improve performance, you can now use in-memory mode, so that messages are stored in memory instead of persisted in the message store.
- You can now subscribe to durable topics, which persist messages so that if a subscriber is not online, it can receive the messages later. A durable topic subscription is useful when an application needs to be able to receive messages that are published even when the application is inactive.
- You can now specify the maximum delivery attempts to restrict the number of times a message delivery is attempted. When a message is successfully delivered on a redelivery attempt, the new JMSRedelivered field is set to true in the message header, allowing the client to determine whether the message was delivered on its original attempt or on a redelivery attempt.
When browsing queues, you can now display the messages inside a queue, send a test message to a queue, and purge the messages in the queue.
