> *EVENT_OPEN_TXN:*
> *Source Warehouse:*
>  - Create new event type EVENT_OPEN_TXN with related message format etc.
>  - When any transaction is opened either by auto-commit mode or multi-statement mode, need to capture this event.
>  - 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.
>  - Open a txn in target warehouse.
>  - Create a map of source txn ID against target txn ID and persist the same in metastore. There should be one map per replication policy (DBName.* incase of DB level replication, DBName.TableName incase of table level replication)
