Write to persistence store happens once for each update, regardless of cache mode and number of backups. In case of write-behind it always happens on primary node. In case of write-through it depends on atomicity mode: ATOMIC cache will call the store from primary node as well, but TRANSACTIONAL cache will call the store from the node that initiated the update (or transaction). -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Persistent-CacheStore-and-backups-tp1368p1369.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
