NO Security vulnerability in Percona Server / XtraDB Cluster provided binaries

Many of you heard of this nasty security vulnerability in MySQL, and as we are getting a lot of inquiries how does it affect Percona Server, I decided to address it in this post. The issue exists in the source code of MySQL 5.5.23 or earlier and MySQL 5.1.62 or earlier. The same is true […]

Introducing Zend DBi as a MySQL Replacement on IBM i

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 […]

Innodb vs MySQL index counts

I had a customer recently who a few strange errors in their mysqld.err log:

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 […]

Previously we had XtraBackup Windows binaries for 1.0 and 1.2 releases, and they were based on Cygwin compilation of MySQL. After MySQL 5.5 moved to CMake, and cygwin compilation is not supported anymore, it took some efforts for us to come up with native Windows builds, but they are there already. We consider them “alpha” […]

At Percona, we consider it important not only to have the best peak performance, but also stable and predictable performance. I refer you […]

Stripped MySQL builds, the optimization that isn’t

I usually tell people to use official MySQL builds from MySQL, or from their operating system distribution if they don’t want to do that. (This assumes that there is no compelling reason to use third-party builds such as Percona’s.) Sometimes, though, people want to create their own builds, or use a build that is “optimized” […]

Percona Server scalability on multi-cores server

We now have hardware in our test lab that represents the next generation of commodity servers for databases. It’s a Cisco UCS C250 server, powered by two Intel Westmere CPUs (X5670 @ 2.93GHz). Each CPU has 6 cores and 12 threads. The most amazing part is the amount of memory. It has 384GB of RAM, which is […]
