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 […]

You might have heard that Oracle made the decision not to support MySQL for IBM i any longer. This is certainly understandable. However, there are still users who want to continue running IBM i and MySQL. That’s why we’re happy to announce that we have assisted Zend to introduce Zend DBi as a drop-in replacement […]
I had a customer recently who a few strange errors in their mysqld.err log:
[ERROR] Table database_name/table_name contains 8 indexes inside InnoDB, which is different from the number of indexes 7 defined in the MySQL
This customer was running Percona Server 5.1 and they got this error on two tables during a maintenance window when they were adding indexes to the same tables. We had a suspicion that it had something to do with Fast […]
When I started with MySQL 3.22 I would start running MySQL from early beta (if not alpha) and update MySQL the same date as release would hit the web. Since that time I matured and so did MySQL ecosystem. MySQL is powering a lot more demanding and business critical applications now than 12 years ago […]
As we can see, MySQL 5.5.8 comes with great improvements and scalability fixes. Adding up allÂ the new features, you haveÂ a great release. However, there is one area I want to touch on in this post. At Percona, weÂ consider itÂ important not only to have the best peak performance, butÂ also stable and predictable performance. I refer you […]
We had too many requests for deb builds of Percona releases so I could not ignore that and added scripts to build binaries on our Ubuntu 8.10 box. It’s going to be only 64bit releases (32bit is dead, isn’t it?), and I tested binaries on Debian Lenny system and it seems working fine. So I […]
These days I’m working with a customer who has an application based entirely on stored routines on MySQL side. Even though I haven’t worked much with stored procedures, I though it’s going to be a piece of cake. In the end – it was, but there’s a catch.
We made new binaries for MySQL 5.0.67 build 10 which include next fixes: We addressed concerns about potential logging and statistics overhead, so now you can fully turn on / off query statistics for microslow patch and user statistics in runtime. Next variables were added:
| slow_query_log | ON |
| slow_query_log_file | /var/lib/mysql/slow_query.log |
for compatibility with MySQL 5.1
| userstat_running | OFF |
to control gathering of user statistics.
With both slow_query_log = OFF and userstat_running = OFF […]
We’ve recently done benchmarks comparing different MySQL versions in terms of their CPU efficiently in TPC-C like Workload. We did it couple of weeks ago so MySQL 5.0.67, MySQL 5.1.29 and Innodb Plugin 1.0.1 were used which are not very recent, though we do not think results will differ a lot with today versions.
We made new patches, improved previous and want to announce new builds for 5.0.62, 5.0.67 and 5.1.26 versions. One of biggest changes we separated releases of 5.0 into two branches. First, just “-percona” release is more stable and contains only stable and proven on many installation patches. Second is “-percona-highperf” release, which contains experimental patches […]
