[jira] [Created] (QPID-3603) New approach to HA
New approach to HA
------------------
Key: QPID-3603
URL: https://issues.apache.org/jira/browse/QPID-3603
Project: Qpid
Issue Type: Improvement
Affects Versions: 0.14
Reporter: Alan Conway
Assignee: Alan Conway
The existing cluster code suffers from some maintainability and performance problems. This is a proposal to write a new HA solution based on the "replicating subscription" that will replace the current cluster. This is a competing proposal to QPID-2920.
Summary: a "replicating subscription" is a special queue browser that can see acquired and un-acquired messages and also receives dequeue events to replicate remote queue contents. The new HA solution will create & manage these subscriptions in order to maintain a back-up of a primary broker on one or more back-up brokers. This is an active-passive hot-standby configuration, where exactly one broker is primary and the others are secondary. Initially plan is to use Cluster Suite's rgmanager to enforce the roles and manage fail-over, but we could support other cluster resource managers (e.g. PaceMaker) in the future.
