> 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.
