Right, if there's no definition for the transaction, there will be an implicit transaction, otherwise, explicit one will be used. >2) ignite uses entry lock level, so in your case, there should be no crossing between transactions, so I don't see the reason why transaction should fail. Do you think you can share reproducer or at least full logs with stacktraces? Thanks, Mike. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
