As promised Rob Young over at Oracle’s Mysql blog has provided us with one more Mysql 5.5 writeup. This time the focus is on some of the new features that you can expect from Mysql 5.5.

Here are the topics covered by Rob’s post:

• Semi-synchronous Replication
• Replication Heartbeat
• Automatic Relay Log Recovery
• Replication Per Server Filtering
• Replication Slave Side Data Type Conversions

These are exciting changes, that many people have been looking forward to for quite some time. Including these features in 5.5 will help make sure that replication is even more reliable and more manageable in the future.
