I previously blogged about work I was doing on automatically finding problems in a MySQL server, with no hardcoded thresholds or predetermined indicators of what is “bad behavior.” I had to pause my studies on that for a while, due to time constraints. I’ve recently been able to resume and I’m happy to report that I’m making good progress.
The second edition of High Performance MySQL has 27 reviews on Amazon, but the third edition only has 5 so far. By this point I assume many of you have a copy and have read it cover to cover. I’d really appreciate your reviews — when purchasing, people look not only at the star rating but at the number of reviews. You can create a review here. And thanks!
While doing a performance audit for a customer a few weeks ago, I tried to improve the response time of their top slow query according to
pt-query-digest‘s report. This query was run very frequently and had very unstable performance: during the time data was collected, response time varied from 50µs to 1s.
I’ve been helping customers deploy and maintain MySQL (and variants) for the last couple of years and it has always been interesting to hear customer thoughts on how they want their servers installed. It has also been asked many times not only by our support and consulting customers, but widely from different forums and blogs – how should I install MySQL on my server and what pros and cons does each have?
Intel came on PCI-e SSD market with their Intel SSD 910 card. With a slogan “The ultimate data center SSD” I assume Intel targets rather a server grade hardware, not consumer level.
I’ve got one of this card into our lab. I should say it is very price competitive, comparing with other enterprise level PCIe vendors. For a 400GB card I paid $2100, which gives $5.25/GB. Of course I’ve got some performance numbers I’d like to share.
MySQL is a great database server. It has lots of flaws, but if you work with its strong points and try to minimize its weaknesses, it works fantastically well for a lot of use cases. Unfortunately, if you bang on its weak points, sometimes you get hit by falling bricks.
