In case you’ve been living under a rock for the last 5 years, the NoSQL movement has changed. There was a time when everyone – EVERYONE – was dumping on relational databases, and MySQL in particular. Nonsense like “SQL itself is inherently unscalable” routinely came out of the mouths of otherwise usually sensible people. But that’s cooled off a little bit, thank heavens. And what’s the new hotness? Well, Big Data, of course!

Percona Toolkit 2.1.8

Percona Toolkit 2.1.8 was released today and the new version comes with some pretty cool news: Beta support for MySQL 5.6 (which as you might know is also in beta).

In addition to various bug fixes, Percona Toolkit 2.1.8 also offers beta support for Percona XtraDB Cluster (PXC). Version 2.1.8 continues the trend of solid bug fix releases, and all 2.1 users are encouraged to upgrade.

You can download Percona Toolkit 2.1.8 here.  (More info on Percona Toolkit). Users who plan on running the tools on Percona XtraDB Cluster or MySQL 5.6 are advised to upgrade. …

While we do have many blog posts on replication on our blog, such as on replication being single-threaded, on semi-synchronous replication or on estimating replication capacity, I don’t think we have one that covers the very basics of how MySQL replication really works on the high level. Or it’s been so long ago I can’t even find it. So, I decided to write one now.

Of course, there are many aspects of MySQL replication, but my main focus will be the logistics – how replication events are written on the master, how they are transferred to the replication slave and then how …

How To Install Percona Server 5.5 On Ubuntu 12.10

Percona Server is a drop-in replacement for MySQL. It offers more performance and scalability than the default MySQL server coming with your Linux distribution, while it uses the same init scripts and command line tools which makes it easy to use. This tutorial explains how to install Percona Server 5.5 on Ubuntu 12.10.

I think it’s worth noting that since January 2012 there was no changes to MHA (0.53). Yoshinori Matsunobu made two releases in December (release notes), one in time for my Percona Live London 2012 talk. Thanks Yoshi! Totally download MHA 0.55 which is still be actively developed & used in production at multiple locations.

We are excited to announce TokuDB® v6.6, the latest version of Tokutek’s flagship storage engine for MySQL and MariaDB.

This version offers three types of performance improvements: in-memory, multi-client and fast updates.

Although TokuDB is optimized for large tables, which are larger than memory, many workloads consist of a mix of large and small tables. TokuDB v6.6 offers improvements on in-memory performance, with a more than 100% improvement on Sysbench at many concurrency levels and more than 200% improvement on TPC-C at many concurrency levels. Details to follow.

We have also made improvements in multi-threaded performance. For example, single threaded trickle loads have always been fast in TokuDB. But now multi-threaded trickle loads are even faster. An iibench run with four writers shows an increase from ~18K insertions/sec to ~28K …
