Val In the case of the primary failure, it send out a EVT_NODE_FAILED event, is the CacheStoreSessionListener.onSessionEnd() method still be called? Which one goes first, the event or the onSessionEnd() method?
Thanks again Shaomin -----Original Message----- From: vkulichenko [mailto:[email protected]] Sent: 19 April 2016 21:56 To: [email protected] Subject: RE: Data lost when using write-behind Shaomin, The EVT_NODE_FAILED is fired when any node fails and leaves topology, but you still don't know which entries are lost because you lost the write-behind queue that was on that node. Currently the only way to fully guarantee consistency between cache and DB is using write-through. After [1] is fixed, this will be also possible with write-behind in ATOMIC caches. But in TRANSACTIONAL caches write-behind store makes all DB updates separately, losing the transactional semantics on DB level, so inconsistencies will still be possible.
