As my first contribution to the MySQL Performance Blog, I joined Percona at the beginning September, I chose to cover the various high-availability (HA) options available for MySQL. I have done dozen of MySQL HA related engagements while working for Sun/MySQL over the last couple of years using Heartbeat, DRBD and NDB cluster and I’ll [...]

Is DRBD the right choice for me?
July 7, 2009 By 18 Comments
It seems pretty common to find customers install DRBD for the wrong reasons. There are many pros/cons to compare DRBD to replication, but I’ve managed to cut down my spiel I give to customers to these two points: DRBD’s aim (assuming replication mode C) is to provide 100% consistency, and then as much uptime as [...]

When would you use SAN with MySQL ?
March 9, 2009 By 18 Comments
One question which comes up very often is when one should use SAN with MySQL, which is especially popular among people got used to Oracle or other Enterprise database systems which are quite commonly deployed on SAN. My question in such case is always what exactly are you trying to get by using SAN ?
Faster MySQL failover with SELECT mirroring
February 1, 2009 By 9 Comments
One of my favorite MySQL configurations for high availability is master-master replication, which is just like normal master-slave replication except that you can fail over in both directions. Aside from MySQL Cluster, which is more special-purpose, this is probably the best general-purpose way to get fast failover and a bunch of other benefits (non-blocking ALTER [...]
How much overhead DRDB could cause ?
June 2, 2008 By 4 Comments
I was working with the customer today investigating MySQL over DRBD performance issues. His basic question was why there is so much overhead with DRBD in my case, while it is said there should be no more than 30% overhead when DRBD is used. The truth is – because how DRBD works it does not [...]
MySQL Replication vs DRBD Battles
April 28, 2008 By 12 Comments
Well these days we see a lot of post for and against (more, more) using of MySQL and DRBD as a high availability practice. I personally think DRBD has its place but there are far more cases when other techniques would work much better for variety of reasons. First let me start with Florian’s comments [...]
State of MySQL Market and will Replication live ?
April 9, 2008 By 29 Comments
There are interesting posts these day about future of MySQL Replication by Brian Frank and Arjen. I think it very interesting to take a look at a bit bigger picture using framework from Innovators Dilemma and Innovators Solution. I’m not going to speak about disruption and commoditisation of Database Market, leaving this for Market talks, [...]
MySQL Northern European Customer Conference
October 17, 2007 By 7 Comments
Yesterday I’ve attended MySQL Customers Conference in London. This event is much smaller size than Users Conference (one day and about 170 people attending) and surely less geeky – there were no one from MySQL Development Support or Consulting teams and Sales Engineers were as close as you could get. Though Anders Karlsson and Ivan [...]
