> 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.
