[infinispan-issues] [JBoss JIRA] Commented: (ISPN-370) clear the store before state transfer

[Manik Surtani (JIRA)]

    [ https://jira.jboss.org/jira/browse/ISPN-370?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12529348#action_12529348 ] 

Manik Surtani commented on ISPN-370:
------------------------------------

the cache store is now always cleared before the state transfer process begins.  This will prevent stale state from being picked up.  And any store impls that attempt a clear() within fromStream() have been refactored to not do this.

Regarding a configurable policy on clearing, if there is demand we can add this later.  For now it always clears before applying state.

> Right now, before integrating state (fetch persistent state = true) the cacheStore.clear() is performed within cacheStore. This cacheStore.clear() should be moved outside the store, in StateTransferManager, and state transfer should document that the the store is cleared before integrating remote state.
