Subject [jira] Resolved: (AMQ-2927) Implement custom brokerId assignment strategy
Date Wed, 22 Sep 2010 13:23:41 GMT


Dejan Bosanac resolved AMQ-2927.

    Fix Version/s: 5.5.0
       Resolution: Fixed

Fixed with svn revision 999924.

Now it's possible to configure custom broker id in the config file, like

<broker xmlns="" brokerName="brokerA" brokerId="brokerA">

This will ensure that broker always has the same broker id and prevent problems with duplicate
routes in network when broker is restarted.

Extra caution is needed to avoid having multiple brokers with the same ID.

> In network of brokers, duplicate route detection is done by checking broker ids. After
the restart, the broker ids change, which can cause duplicate routes and messages stuck due
to reached ttl.
> We need to provide a mechanism for users to configure how their broker ids are assigned
and make sure that they stay the same after the restart. Which will ensure correct duplicate
route detection even after some of the broker in the mesh is restarted.
