I don’t use many tools in my consulting practice but for the ones I do, I try to know them as best as I can. I’ve been using mk-query-digest for almost as long as it exists but it continues to surprise me in ways I couldn’t imagine it would. This time I’d like to share [...]
High Rate insertion with MySQL and Innodb
January 7, 2011 By 17 Comments
I again work with the system which needs high insertion rate for data which generally fits in memory. Last time I worked with similar system it used MyISAM and the system was built using multiple tables. Using multiple key caches was the good solution at that time and we could get over 200K of inserts/sec. [...]
Two Types of MySQL Users
May 10, 2010 By 5 Comments
In comments to my previous post I got number number of comments saying if MySQL would not have multiple storage engine interface it would not allow people to do various very cool stuff. And I agree with this. The question is how cool you want your database operation to be ? Visiting customers I see [...]
MongoDB Approach to database synchronization
April 30, 2010 By 5 Comments
I went to MongoSF today – quite an event, and I hope to have a chance to write more about it. This post is about one replication problem and how MongoDB solves it. If you’re using MySQL Replication when your master goes down it is possible for some writes to be executed on the master, [...]

Great work Innodb Team
November 30, 2009 By 8 Comments
I thought I should praise Innodb team for all the work they have been doing recently. We see a lot of cool stuff happening, especially in the area of our interest which is Performance And Scalability. Innodb Plugin 1.0.4 had a lot of great performance improvements and 1.0.5/1.0.6 gets even further with long standing caching [...]
MySQL-Memcached or NOSQL Tokyo Tyrant – part 1
October 15, 2009 By 16 Comments
All to often people force themselves into using a database like MySQL with no thought into whether if its the best solution to there problem. Why? Because their other applications use it, so why not the new application? Over the past couple of months I have been doing a ton of work for clients who [...]
mk-query-digest, query comments and the query cache
I very much like the fact that MySQL allows you to embed comments into SQL statements. These comments are extremely convenient, because they are written into MySQL log files as part of the query. This includes the general log, the binary log and the slow query log. Maatkit includes tools which interact with these logs, [...]
