------------------------------------
Summary: selectorAware subscription cache replication
Key: AMQ-5546
URL: https://issues.apache.org/jira/browse/AMQ-5546
Project: ActiveMQ
Issue Type: Bug
Affects Versions: 5.10.0
Environment: ActiveMQ 5.10.0
Replica Leveldb Cluster
Reporter: Pankaj Takawale
AMQ Replica LevelDB cluster does not replicate VirtualTopic Subscriber's
selector expression. So on consumer disconnect followed by failover, new master
does not have consumer's selector expression. It causes consumer to miss
messages published during its offline duration.
Steps to reproduce:
1. consumer subscribes (JMSSelector filter)
2. producer publishes
3. consumer consumes
4. consumer disconnects (offline)
5. Activemq *failover* occurs (new master gets elected)
6. producer publishes
7. consumer reconnects ( missed messages during offline period)
I poked around SelectorAware cache code. It persists selector cache to local
filesystem, that never gets replicated to slave nodes.
Possible solution is to persists subscription info to leveldb, so that it gets
replicated.
