[ https://issues.jboss.org/browse/TEIID-2578?page=com.atlassian.jira.plugin... ] Ramesh Reddy commented on TEIID-2578: ------------------------------------- In this singleton service scheme, only master should have the persistent copy of VDBs, so if non-master node comes up it should be empty to start with. As soon as master node starts it should replicate the events. (atleast that is what I think :) ), but issue could be, what if master node went down in-between and comes back up, it is going to duplicate the state, that needs to be avoided. I did not add any provision for this, IMO we need to maintain a VDB wide version/lastmodified number that can be passed with *all* EventDistributor methods. aka. like a if-match-none HEADER in http, What do you think? -- This message was sent by Atlassian JIRA (v6.4.11#64026)
