My last post about Innodb Performance Optimization got a lot of comments choosing proper innodb_buffer_pool_size and indeed I oversimplified things a bit too much, so let me write a bit better description. Innodb Buffer Pool is by far the most important option for Innodb Performance and it must be set correctly. I’ve seen a lot [...]
OK, I am not getting too much people feedback on what would they like to hear about on MySQL Users Conference, so I went ahead and submitted few presentation ideas. I do not expect all of them would be accepted, furthermore it would be hard to prepare so many good presentations if they are so [...]
About three months ago I announced ClickAider to become available to general public. And I think it is about the time to write about the progress we have with this project for those who interested. The project generates decent interest and we have about 3000 sites Registered over this time, which I consider decent number [...]
Quite frequently I run into question like this “I’m using SQL_NO_CACHE but my query is still much faster second time I run it, why is that ? The answer to this question is simple – because SQL_NO_CACHE only bypasses query cache but it has no change on other caches, which are MySQL Caches – Innodb [...]
I finally found a time to publish Landscape of Transactional Storage Engines slides on MySQL Presentations page , this is the talk which we gave on OSCON 2007 and which talks about current state behavior and performance properties of Innodb, Falcon, PBXT and SolidDB Storage Engines.
Let me announce ClickAider – another projects we were working on in stealth mode for last several Months. ClickAider is Hosted Web Statistics system but it tracks Clicks rather than page views as most web counters do. And by clicks I mean not just clicks on the urls and images but clicks on many sophisticated [...]
Vadim and me will be speaking on OSCON 2007, taking place in Portland,OR July 23-27. Our talk will be about Open Source Transactional Storage Engines meaning Innodb, Falcon, Solid and PBXT. We’ll look into architecture of these storage engines as well as compare performance in number of Benchmarks. If you will be visiting OSCON please [...]
Today everybody writes about MySQL Conference & Expo and I am not an exclusion. I am under impression of count of storage engines were presented. In good old time when Oracle bought InnoDB, MySQL did one step – announced MySQL supports Plugginable Storage Architecture. In that time nobody was able to predict what is the [...]
I can’t write I’m just back from MySQL Users Conference both because I’m still in USA visiting customers and because it has ended almost a week ago but I was too busy to write anything about it or post my presentations. This was my 5th MySQL Users Conference so I met a lot of good [...]
The PBXT Storage Engine (http://www.primebase.com/xt/) is getting stable and we decided to benchmark it in different workloads. This time I tested only READ queries, similar to ones in benchmark InnoDB vs MyISAM vs Falcon (http://www.mysqlperformanceblog.com/2007/01/08/innodb-vs-myisam-vs-falcon-benchmarks-part-1) The difference is I used new sysbench with Lua scripting language, so all queries were scripted for sysbench.
