The add-on allows you to receive information about Spring container events from any application block of the distributed system.
In the simple configuration running in a single JVM you can send events from
web blocks to notify UI screens or managed beans. In a cluster environment, an event published inside a block will be received in middleware blocks and in the
portal client blocks.
- Asynchronous events delivering, including the local deployment.
- Accurate ordering only within a block.
- There is no retransmit — delivery in the distributed deployment is guaranteed “at most once”.
- In the distributed deployment the web block starts receiving notifications once a user is connected.
