Replication Of Transaction

Reported by Andreas Ronge | June 26th, 2009 @ 11:39 AM

Currently replication does not know if an transaction has been replicated or not.
It simply just replicate the last transaction found on the master.
The slave should compare the version of the master transaction (ETag) with what has previously been replicated
and replicate all transaction that has not been already replicated.

Should use HTTP Etag to store which transaction has been replicated
See the HTTP Etag Ticket
