We have been working on bringing out a build of MyRocks with Percona Server for MySQL.

MyRocks is a RocksDB-based storage engine. You can find more information about MyRocks here.

While there is still a lot of work to do, I want to share an experimental build of Percona Server for MySQL with MyRocks, which you can use to evaluate and test this engine

(WARNING: in NO WAY is this build supposed to be for production usage! Consider this ALPHA quality.)

The tar.gz binaries are available from our …

If you met one of the (few) MySQL consultants around the globe and asked him/her to review your queries and/or schemas, I am sure that he/she would tell you something regarding the importance of good primary key(s) design. Especially in the case of InnoDB, I’m sure they started to explain to you about index merges and page splits. These two notions are closely related to performance, and you should take this relationship into consideration when designing any index (not just PKs).

That may sound like mumbo jumbo to you, and you may be right. This is not easy stuff, especially when talking about internals. This is not something you deal with on a regular basis, and often you don’t want to deal with it at all.

But sometimes it’s a necessity. If so, this article is for you.

In this article, I want to shed some light in explaining some of the most unclear, behind the scenes operations in InnoDB: page index …

In this blog post, we’ll point to a new Docker image for Percona Server for MySQL Group Replication.

Our most recent release of Percona Server for MySQL (Percona Server for MySQL 5.7.17) comes with Group Replication plugins. Unfortunately, since this technology is very new, it requires some fairly complicated steps to setup and get running. To help with that process, I’ve prepare Docker images that simplify its setup procedures.

You can find the image here: https://hub.docker.com/r/perconalab/pgr-57/.

To start the first node (bootstrap the group):

docker run -d -p 3306 --net=clusternet -e …

Please join Laurynas Biveinis, Percona’s Technical Director – Engineering, on January 25, 2017, at 7 am EST (UTC-8) as he discusses “Percona Server for MySQL 5.7: Key Performance Algorithms.”

In this webinar, Laurynas will discuss selected areas of InnoDB and Percona Server for MySQL 5.7 internals as they relate to buffer pool management and flushing (from a performance and scalability point of view). He will describe the motivation behind the buffer pool mutex split, multi-threaded LRU flusher and parallel doublewrite features in Percona Server for MySQL 5.7, given that MySQL InnoDB 5.7 has re-implemented many of the same features found in Percona Server for MySQL – especially …

In this blog post, we’ll look at how to replace MySQL with Percona Server for MySQL on a CPanel, WHM VPS or dedicated server.

In general, CPanel and WHM have been leaning towards support of MariaDB over other flavors. This is partly due to the upstream repos replacing the MySQL package with MariaDB (for example, on CentOS).

MySQL 5.6 is still supported though, which means they are keeping support for core MySQL products. But if you want to get some extra performance enhancements or enterprise features for free, without getting too many bells and whistles, you might want to install Percona Server.

I’ve done this work on a new dedicated server with the latest WHM and CPanel on CentOS 7, with MySQL 5.6 installed. …
