Forking MySQL/ for how long can forks keep up?
+13 Vote Up -3Vote Down
  • Fact: MySQL 5.6 was released as GA in February 2013
  • Fact: MySQL 5.6 has been available with its complete set of features since September 2012
  • Fact: On September 21st, Oracle has released MySQL 5.7.2, which is the de facto major release after MySQL 5.6 (5.7.1 was just a token “we’re-still-in-business” release).
  • Fact: As of today, there is no GA-ready fork of MySQL 5.6.

Percona Server is still in RC state, while MariaDB, with its runaway version 10, is still in alpha state. Of …

Are MariaDB tests adding anything extra over Oracle MySQL tests?
+3 Vote Up -0Vote Down

I grabbed all the tests introduced in MariaDB 5.5.32 (i.e. “bzr diff -rtag:mariadb-5.5.31..mariadb-5.5.32 mysql-test/” and some foo) and threw them in their own test file. I only kept tests for crashing bugs and ignored those that required plugins (there were two or three, but nothing major). So now I have a test file that should crash MariaDB 5.5.31 and probably before. But, the question is: does this crash Percona Server or MySQL?

While it is excellent to see the MariaDB guys including tests for …

pt-query-digest for MongoDB profiler logs
+2 Vote Up -0Vote Down

One of my favorite MySQL tools ever is pt-query-digest. It's the tool you use to generate a report of your slow query log (or some other supported sources), and is similar to for example the Query Analyzer in MySQL Enterprise Monitor. Especially in the kind of job I am, where I often just land out of nowhere on a server at the customer site, and need to quickly get an overview of what is going on, this tool is always the first one I run. I will show some examples below.

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 …

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 …

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 …

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 …

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.
