MySQL Monitoring With Cacti Using Percona Monitoring Plugins (1-minute resolution)
+0 Vote Up -0Vote Down

Today, just like many times before, I needed to configure a monitoring server for MySQL using Cacti and awesome Percona Monitoring Templates. The only difference was that this time I wanted to get it to run with 1 min resolution (using ganglia and graphite, both with 10 sec resolution, for all the rest of our monitoring in Swiftype really spoiled me!). And that’s where the usual pain in the ass Cacti configuration gets really amplified by the million things you need to change to make it work. So, this is a short checklist post for those who need to configure a Cacti server with 1 minute resolution and setup Percona Monitoring Plugins on it.

Configuring Cacti for 60-seconds polling

Percona has more MariaDB features now
+3 Vote Up -0Vote Down

Lately more people ask me for comparisons between Percona Server & MariaDB. There isn’t a definitive blow-by-blow feature comparison yet, but it’ll come soon.

All that said, its great to see new features from MariaDB make it into Percona Server. The features that I’ve managed to track: group commit for the binary log, threadpool and atomic write support for Fusion-io devices.

It started with the group commit for the binary log feature in Percona Server 5.5.18-23.0 (

TokuDB vs Percona XtraDB using Tokutek’s MariaDB distribution
+1 Vote Up -0Vote Down

Following are benchmark results comparing Tokutek TokuDB and Percona XtraDB at scale factor 10 on the Star Schema benchmark. I’m posting this on the Shard-Query blog because I am going to compare the performance of Shard-Query on the benchmark on these two engines. First, however, I think it is important to see how they perform in isolation without concurrency.

Because I am going to be testing Shard-Query, I have chosen to partition the “fact” table (lineorder) by month. I’ve attached the full DDL at the end of the post as well as the queries again for reference.

I want to note a few things about the results:
First and foremost, TokuDB was configured to use quicklz compression (the default) and InnoDB compression was not used. No tuning of TokuDB was performed, which means it will use up to 50% of memory by

5 years of MySQL

People often write a blog post when they reach some nice anniversary since they joined MySQL community. Well, for those old enough it usually means when they joined MySQL AB as employee. For me this was January 2008. Because I didn't remember the month correctly, I haven't blogged anything then, but decided to save it for a better opportunity - now.

TL;DR Starting this week I will be working for 10gen, selling MongoDB to the Nordics. This blog post is really long - even then it doesn't contain the most interesting stories, I'm not sure if they can ever be published. Sorry for the length, but remember you don't need to read all at once. This is my last MySQL post so save some of it for cold winter days!

Slides from Failover or not Failover, that is the question
+0 Vote Up -0Vote Down

Below are the slides from my last talk at this Percona Live Worldwide MySQL Conference. The idea for this talk was proposed by my co-presenter Massimo Brignoli and goes back to a debate on this topic that went through the MySQL blogosphere during last Autumn - which in itself was sparked by an outstanding retrospective published about a MySQL failure at Github.

It's time again to award persons, applications and companies in the MySQL Community. This is an annual tradition to highlight and give appreciation to some of the things that make MySQL so great.

The first awards were given out in 2005, and since 2010 the winners have been chosen by a community panel of which myself and Shlomi Noach are the co-secretaries. There has been a public nomination period in January and the final voting is done by a panel who are themselves former winners of the award.

The first category is

The MEMORY storage engine
+3 Vote Up -0Vote Down

I recently wrote about Where are they now: MySQL Storage Engines and The MERGE storage engine: not dead, just resting…. or forgotten. Today, it’s the turn of the MEMORY storage engine – otherwise known as HEAP.

This is yet another piece of the MySQL server that sits largely unmaintained and unloved. The MySQL Manual even claims that it supports encryption… with the caveat of having to use the SQL functions for encryption/decryption rather than in the engine itself (so,

Hiring: Perl programmer, PHP programmer, UI/UX consultant
+0 Vote Up -0Vote Down

I don’t get to say this often, but “I’m hiring” (at Percona):

I’ve been with Percona for about 5 years, so I can tell you: it’s probably the best company to work at: great pay, great benefits, great people, and truly driven by a desire to do right by customers and do good work.  What more can you ask for?  Of course, all these jobs are MySQL-related: Perl + MySQL, PHP + MySQL–maybe the UI/UX job less so, but still close enough.
