Using MySQL 5.6 Global Transaction IDs (GTIDs) in production: Q&A

Thank you to all of you who attended my webinar last week about Global Transaction IDs (GTIDs), which were introduced in MySQL 5.6 to make the reconfiguration of replication straightforward. If you missed my webinar, you can still listen to the recording and download the sides (free). We had a lot of questions during the […]

How to use MySQL Global Transaction IDs (GTIDs) in production

Reconfiguring replication has always been a challenge with MySQL. Each time the replication topology has to be changed, the process is tedious and error-prone because finding the correct binlog position is not straightforward at all. Global Transaction IDs (GTIDs) introduced in MySQL 5.6 aim at solving this annoying issue. The idea is quite simple: each […]

Global Transaction ID and other patches available!

I do not know if you noticed it, but Google (Mark Callaghan, Justin Tolmer and their internal mysql-team) made a great contribution to MySQL. Patches global transaction IDs, binlog event checksums and crash-safe replication state are separated and published on Launchpad (https://code.launchpad.net/~jtolmer/mysql-server/global-trx-ids). For me it was a big wall in using these patches that they […]

GTIDs in MySQL 5.6: New replication protocol; new ways to break replication

One of the MySQL 5.6 features many people are interested in is Global Transactions IDs (GTIDs). This is for a good reason: Reconnecting a slave to a new master has always been a challenge while it is so trivial when GTIDs are enabled. However, using GTIDs is not only about replacing good old binlog file/position […]

Replication in MySQL 5.6: GTIDs benefits and limitations – Part 1

Global Transactions Identifiers are one of the new features regarding replication in MySQL 5.6. They open up a lot of opportunities to make the life of DBAs much easier when having to maintain servers under a specific replication topology. However you should keep in mind some limitations of the current implementation. This post is the […]

How to create a new (or repair a broken) GTID based slave with Percona XtraBackup

Percona XtraBackup 2.0.7 has been published with support for GTID based replication. As promised, here is the step-by-step guide on how to create a new GTID based slave (or repair a broken one) using XtraBackup. The process is pretty straightforward. 1- Take a backup from any server on the replication environment, master or slave:

How to create/restore a slave using GTID replication in MySQL 5.6

MySQL 5.6 is GA! Now we have new things to play with and in my personal opinion the most interesting one is the new Global Transaction ID (GTID) support in replication. This post is not an explanation of what is GTID and how it works internally because there are many documents about that: http://dev.mysql.com/doc/refman/5.6/en/replication-gtids-concepts.html One […]
