Source Warehouse:

• Create new event type EVENT_ALLOCATE_WRITE_ID with related message format etc.

• Capture this event when allocate a table write ID from the sequence table by ACID operation.

• 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 Allocate table write ID from sequence table

Extend listener notify event API to add two new parameter , dbconn and sqlgenerator to add the events to notification_log table within the same transaction
