The DELTA_WRITE flag should force a remote get during state transfer -------------------------------------------------------------------- Key: ISPN-3184 URL: https://issues.jboss.org/browse/ISPN-3184 Project: Infinispan Issue Type: Bug Affects Versions: 5.3.0.Final Reporter: Dan Berindei Assignee: Dan Berindei Priority: Critical Labels: 620 Fix For: 6.1.0.Final AtomicHashMap and FineGrainedAtomicHashMap, as well as custom DeltaAware implementations, use PutKeyValueCommands with the DELTA_WRITE flag to execute incremental updates. These commands need the previous value of the entry in order to work. If a node is joining and it receives a PutKeyValueCommand with the DELTA_WRITE flag before it has received the value of the affected key, it should do a remote get to retrieve the previous value and apply the change on top of that value, just like we do for conditional commands. Not doing so leads to data loss.
