Based on Luis Soarez &#8211; Replication Team Leader in Oracle &#8211; post. I wanted to play with new set of variables and features in order to understand how new [...]]]></description>

If you haven&#8217;t heard of Tungsten Replicator yet, it&#8217;s an open source database replication engine that can be used to complement or completely [...]]]></description>

		<description><![CDATA[MySQL Replication is a powerful tool and it&#8217;s hard to find a production system not using it. On the other hand debugging replication issues can be very hard and time consuming. Especially if your replication setup is not straightforward and you are using filtering of some kind. Recently we got an alert from our monitoring [...]]]></description>

This server was reporting this issue: Last_Error: Could not parse relay log event entry. The possible reasons are: the master&#8217;s binary log is corrupted (you can check this by running &#8216;mysqlbinlog&#8217; on the binary log), [...]]]></description>
