> *EVENT_ABORT_TXN*
> Source Warehouse:
> - Create new event type EVENT_ABORT_TXN with related message format etc.
> - Capture this event when abort the txn.
> - Repl dump should read this event from EventNotificationTable and dump the
> message.
> *Target Warehouse:*
> - Repl load should read the event from the dump and get the message.
> - Validate if source txn ID from the event is there in the source-target txn
> ID map. If not there, just noop the event.
> - If valid, then Abort the corresponding target txn and remove the entry
> from source-target txn ID map.
> All these new events should be idempotent such that if it is applied twice,
> then second time it should be noop.
