MySQL Semi-Synchronous Replication. See the Magic. Try the Magic.
Employee +7 Vote Up -0Vote Down

+1 Vote Up -0Vote Down

When I read on the internetz that Alex Davies was about the publish a Packt book on MySQL HA I pinged my contacts at Packt and suggested that I'd review the book .

MySQL HA , an alternative approach
+0 Vote Up -0Vote Down

For those who've seen my presentation on MySQL HA, you already know that I often use a multimaster setup with a meta OCF resource that groups my favoured MySQL instance with the service ip , using a meta resource means that pacemaker monitors mysql, but it doesn't actually manage it. It's an approach that works for us.

One of the other approaches I will be looking at soon is the freshly released OCF resource that Florian announced last week.

Back in the days our approach meant we didn't have to use clone resources, which you might …

So about 4 monts ago there was the crazy idea to start a new FOSS event in Belgium targeted at sysadmins.

What started out as an event for local people to meet local people with some local speakers actually ended up being a small local event with some top international speakers on onfiguration mananagement and system administration mixed with a bunch of good local ones !

I had the honour to open the conference with an extremely short version of the Devops talk I gave earlier last year.. extremely short as I knew that over the course of the weekend the topic would reoccur a lot.

Kuassi MENSAH (Head of Product Management Database Technologies, Oracle Corporation) presented the open source Oracle strategy. Linux, MySQL, virtualization, GlassFish, Eclipse, dynamic scripting languages ,... etc . It was well received by the audience.

PBXT Engine Level replication, works!
+7 Vote Up -1Vote Down

I have been talking about this for a while, now at last I have found the time to get started! Below is a picture from my 2008 MySQL User Conference presentation. It illustrates how engine level replication works, and also shows how this can be ramped up to provide a multi-master HA setup.


What I now have running is the first phase: asynchronous replication, in a master/slave configuration. The way it works is simple. For every slave in the configuration the master PBXT engine starts a thread which reads the transaction log, and transfers modifications …
