InnoDB vs TokuDB in LinkBench benchmark
+0 Vote Up -0Vote Down

Previously I tested Tokutek’s Fractal Trees (TokuMX & TokuMXse) as MongoDB storage engines – today let’s look into the MySQL area.

I am going to use modified LinkBench in a heavy IO-load.

I compared InnoDB without compression, InnoDB with 8k compression, TokuDB with quicklz compression.
Uncompressed datasize is 115GiB, and cachesize is 12GiB for InnoDB and 8GiB + …

MySQL Admin 101 for System Admins – key_buffer_size
+0 Vote Up -0Vote Down

As discussed in my presentation to NYLUG, I wanted to provide system administrations with some really quick analysis and performance fixes if you had limited knowledge of MySQL.

One of the most important things with MySQL is to tune memory properly. This can be complex as there are global buffers, and per session buffers, memory tables, and differences between storage engines. Even this first tip has conditions.

Configuration of MySQL can be found in the my.cnf file (How can I find …

How MariaDB makes Stored Procedures usable
+4 Vote Up -0Vote Down

I already wrote how MariaDB makes the debug of stored procedures much easier via the SQL Error Log. But I recently found out that MariaDB provides a usable workaround for some big limitations of their procedural SQL.

First, SELECT is not the only SQL statement which returns a resultset. Other examples are DELETE RETURNING, CALL, SHOW, …

MariaDB/MySQL: Making ENGINE clause mandatory
+0 Vote Up -1Vote Down

I got this idea from a Valerii Kravchuk’s MySQL bug report:

In theory, I completely agree that MySQL and forks should not allow us to set a default storage engine which cannot be used to create a table. You can see the same with MariaDB’s SEQUENCE. The MySQL & forks philosophy seems to be: ignore your mistakes, so you can repeat them forever. Which can turn a mistype into a major data loss.

Unless you only use InnoDB and your magic powers tell you that this will never change, …

MariaDB storage engines

This is a list of MariaDB storage engines that are not distributed with MySQL. I think that most of them will work with MySQL, but not all – at least CassandraSE doesn’t.

Plugins & Storage Engines Summit for MySQL/MariaDB
+1 Vote Up -0Vote Down

As is tradition after the O’Reilly MySQL Conference & Expo, there tends to be a storage engine summit right afterwards. This year it was expanded to also include plugins. I must graciously thank Facebook for hosting us at their campus, and giving us a rather healthy lunch, plus fueling us with all those drinks, caffeine and snacks that we needed to keep us going. While standing in the doorway, Mark (Callaghan) pointed to us that a certain other Mark (Zuckerberg) was walking into the campus, just like the rest of …

MySQL 5.1.46 With InnoDB Plugin Kicks Butt
+2 Vote Up -1Vote Down

We were discussing the recommendations we issue each quarter around MySQL and the question of using InnoDB plugin came up. We usually follow Planet MySQL closely, so we read what the blogs had to say and it was all good, but we decided to provide our users some data of our own. We used our own sysbench tests on to get the information we needed.
A Word About BenchmarksI don't trust most of the benchmarks that are published online because they really apply to the use case of whomever is writing the article. They are usually many …

The Doom of XtraDB and Percona Server?
+7 Vote Up -5Vote Down

In The Doom of Multiple Storage Engines, Peter talks about how the storage engine concept of MySQL is usually spoken of in positive terms, but there are many negatives.

I have a hard time trying to figure out the deeper meaning behind Peter’s post, given that Percona writes a storage engine for MySQL, XtraDB. Does this mean that Percona will stop developing XtraDB? Does this mean that the Percona Server will diverge farther and farther away from MySQL so that they’re not compatible any more and migrating from MySQL to Percona Server …
