Subject [jira] [Updated] (QPID-3917) Refactor VirtualHost/MessageStore implementations to be ready for BDB-HA
Date Fri, 30 Mar 2012 07:20:35 GMT

     [ https://issues.apache.org/jira/browse/QPID-3917?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Keith Wall updated QPID-3917:
-----------------------------

    Description: 
Refactor the VirtualHost and MessageStore implementations ready to support the BDB HA (High
Availability) Store:

https://cwiki.apache.org/confluence/display/qpid/Java+Broker+Design+-+HA+using+BDB

The principal change is to allow the store recovery phase to be executed many times during
the lifetime of a virtual host.  This is required for stores such as BDB HA where it is the
store itself that decides when it becomes master.
