MySQL Marinate for the Holiday Season

Just a friendly reminder that you can pick up MySQL Marinate whenever you want! You can use the master list at http://www.meetup.com/Virtual-Tech-Self-Study/messages/boards/thread/38423162 for reference – just ignore the dates and work at your own pace!

We found that very few people were taking the dates to heart, so we stopped trying to organize around them. The message boards are still valid, so feel free to ask if you have any questions – we are here to help!

MySQL & Friends Devroom FOSDEM 2015

You can already feel the cold of February coming slowly… you can also smell waffles, fries and see a large amount of beards walking around with laptops… you are right, FOSDEM is coming! And as every year, the MySQL Community will also be present!

Refactoring replication topologies with Pseudo GTID: a visual tour

Orchestrator 1.2.1-beta supports Pseudo GTID (read announcement): a means to refactor the replication topology and connect slaves even without direct relationship; even across failed servers. This post illustrates two such scenarios and shows the visual way of mathcing/re-synching slaves.

Orchestrator 1.2.1 BETA: Pseudo GTID support, reconnect slaves even after master failure

orchestrator 1.2.1 BETA is released. This version supports Pseudo GTID, and provides one with powerful refactoring of one's replication topologies, even across failed instances.

Refactoring replication topology with Pseudo GTID

This post describes in detail the method of using Pseudo GTID to achieve unplanned replication topology changes, i.e. connecting two arbitrary slaves, or recovering from a master failure even as all its slaves are hanging in different positions.

Please read Pseudo GTID and Pseudo GTID, RBR as introduction.

Pseudo GTID, Row Based Replication

This post continues Pseudo GTID, in a series of posts describing an alternative to using MySQL GTIDs.

The solution offered in the last post does not work too well for row based replication. The binary log entries for the INSERT statement look like this:

MySQL community set to meet at Percona Live London 2014

The countdown is on for Europe’s largest annual MySQL event, Percona Live London 2014. The two days of technical tutorials and sessions, November 3-4, will focus on the latest MySQL industry trends, news, best practices – and a look at what’s on the near- and long-term horizon within the global MySQL ecosystem.

Pseudo GTID

Pseudo GTID is a method to implement a GTID-like solution where slaves are easily connected to one another. This blog post and the following ones will describe work in progress (some 80% completed), where simulation of GTID makes for a good enough basis for refactoring replication topologies. I'm coding this in orchestrator, which already provides a substantial infrastructure support for this.

Percona XtraDB Cluster: How to run a 2-node cluster on a single server

I reckon there’s little sense in running 2 or more Percona XtraDB Cluster (PXC) nodes in a single physical server other than for educational and testing purposes – but doing so is still useful in those cases. The most popular way of achieving this seems to be with server virtualization, such as making use of Vagrant boxes.
