Description

The transactions opened by applying EVENT_OPEN_TXN should never be aborted automatically due to time-out. Aborting of transaction started by replication task may leads to inconsistent state at target which needs additional overhead to clean-up. So, it is proposed to mark the transactions opened by replication task as special ones and shouldn't be aborted if heart beat is lost. This helps to ensure all ABORT and COMMIT events will always find the corresponding txn at target to operate.
