Hi, Transaction here might be a not optimal solution, as it by default optimistic and may throw optimistic transaction exception. I believe the best solution would be to use EntryProcessor [1], it will atomically modify entry as on TRANSACTIONAL as on ATOMIC cache on affinity data node (that actually keep this entry).
