In this post I provide some tips and advice on how to become a published auther for Oracle, MS SQL Server, and MySQL

I am very excited and thrilled to use the latest release of MySQL 5.6 in production. This is probably the most notable and innovative release in many years, if not ever.

During the last year, we had the chance to work with many new features and test the fixes to old issues. To be honest, I was expecting to have MySQL 5.6 GA before now, and I even wagered with my colleague Francisco that it would be out before the end of 2012. It was nothing special, just a beer in the Santa Clara Hyatt lounge. Unfortunately for me, MySQL 5.6 is now in GA and given that it happened in 2013, I lost the bet and now have to pay for that beer. But I have also lost the full list of things that we saw as relevant, interesting, or really innovative for MySQL.

A few days ago one of our customers contact us to inform a problem with one of their replication servers.

This server was reporting this issue:

Last_Error: Could not parse relay log event entry. The possible reasons are: the master’s binary log is corrupted (you can check this by running ‘mysqlbinlog’ on the binary log), the slave’s relay log is corrupted (you can check this by running ‘mysqlbinlog’ on the relay log), a network problem, or a bug in the master’s or slave’s MySQL code. If you want to check the master’s binary log or slave’s relay log, you will be able to know their names by issuing ‘SHOW SLAVE STATUS’ on this slave.

After brief research we found the customer had deleted some binary logs from the master and relay logs from slave to release space since they were having space issues.

The customer requested us to get slave working again without affecting the production …
