How to improve InnoDB performance by 55% for write-bound loads
+2 Vote Up -0Vote Down

During April’s Percona Live MySQL Conference and Expo 2014, I attended a talk on MySQL 5.7 performance an scalability given by Dimitri Kravtchuk, the Oracle MySQL benchmark specialist. He mentioned at some point that the InnoDB double write buffer was a real performance killer. For the ones that don’t know what the innodb double write buffer is, it is a disk buffer were pages are written before being written to the actual data file. Upon restart, pages in the double write buffer are rewritten to their data files if complete. This is to avoid data file corruption with half written pages. I knew it has an impact on performance, on ZFS since it is transactional I always disable it, but I never realized how important the performance

Percona Live 2014 behind; MySQL ahead
+0 Vote Up -0Vote Down

I started using MySQL 11 years ago.  That’s not too long compared to other people in the industry, but nonetheless here’s my perspective on the state of the MySQL industry after attending Percona Live MySQL Conference & Expo 2104.

In short, the attitude around MySQL has changed from “Does it work?” to “Is it fast and reliable?” to “How do we manage it?” To further generalize, these periods correspond roughly to the original MySQL AB team, Percona and Oracle, and the last period is the current period so key players are emerging, like WebScaleSQL.

Does it work?

ScaleArc: Benchmarking with sysbench
+0 Vote Up -0Vote Down

ScaleArc recently hired Percona to perform various tests on its database traffic management product. This post is the outcome of the benchmarks carried out by Uday Sawant (ScaleArc) and myself. You can also download the report directly as a PDF here.

The goal of these benchmarks is to identify the potential overhead of the ScaleArc software itself and the potential benefits of caching. The benchmarks were carried out with the trunk version of sysbench. For this reason, we used a very small set of data, so the measurements will be fast, and it’s known that caching has huge benefits when the queries themselves are rather expensive. We decided that we would rather show that benefit with a real-world application, which is coming later is this series.

Database security: Why should you review yours?
+0 Vote Up -0Vote Down

Ah database security… the black sheep of topics and something you would really rather not have to deal with right?

I mean surely all the fanfare and paranoia is reserved for the neck beards with tinfoil hats whom live in their own D.I.Y Faraday cage … that must be it … it just has to be?

No, the hard reality is the world is not rose tinted and “they” are out to get you be it for fun or for profit; from defacements to theft compromising your applications, and more importantly your data is big business. For some these acts are nothing short of sheer entertainment for an otherwise boring evening. (I’ll be speaking about this topic next week in much more detail at the Percona Live MySQL Conference and Expo in
