This Weekend in Japan
+0 Vote Up -0Vote Down

We were happy to see a lot of folks from Japan on Twitter this weekend having a discussion about MySQL and Tokutek. While we always endeavor to explain ourselves as simply as possible, hearing what users and peers have to say and ask in their native language is very helpful. Here is a sampling of several of the 30+ tweets and re-tweets (translations courtesy of a colleague I know from frequent past visits to Tokyo and Yokohama):

First, @frsyuki provided a general overview:

Thanks to Mike, a video of the talk is now available:

Tokutek co-founders Bradley, Martin, and I are coauthors on the work, along with students and …

Shard-Query turbo charges Infobright community edition (ICE)
+2 Vote Up -1Vote Down

Shard-Query is an open source tool kit which helps improve the performance of queries against a MySQL database by distributing the work over multiple machines and/or multiple cores. This is similar to the divide and conquer approach that Hive takes in combination with Hadoop. Shard-Query applies a clever approach to parallelism which allows it to significantly improve the performance of queries by spreading the work over all available compute resources. In this test, …

+2 Vote Up -0Vote Down

I had a good and lively audience at my presentation today. I was happy to give them a sneek preview of the Mk.III implementation of OQGRAPH.

Oh yeah! I guess I'm announcing the availability of the source code of the MkIII implementation.

Links are in my slides... http://goo.gl/UrybZ

Btw, building the storage engine requires Boost libraries and libJudy installed. It's currently in a MariaDB

 Just got done with day 1 from the MySQL conf 2011... tutorial day. I decided to attend a session a bit outside of my comfort zone, so I chose MySQL Plugin Development. I haven't written any serious C/C++ for over 10 years, but lately it's been more appealing to me.

Innodb row size limitation
+0 Vote Up -0Vote Down

I recently worked on a customer case where at seemingly random times, inserts would fail with Innodb error 139. This is a rather simple problem, but due to it’s nature, it may only affect you after you already have a system running in production for a while.

Suppose you have the following table structure:

CREATE TABLE example (
id INT UNSIGNED NOT NULL AUTO_INCREMENT,
fname TEXT NOT NULL,
fcomment TEXT,
ftitle TEXT NOT NULL,
fsubtitle TEXT NOT NULL,
fcontent TEXT NOT NULL,
fheader TEXT,
ffooter TEXT,
fdisclaimer TEXT,
fcopyright TEXT,
fstylesheet TEXT,
fterms TEXT,
PRIMARY KEY (id)
) Engine=InnoDB;

Now you insert some test data …

PBXT early impressions in production use
+3 Vote Up -2Vote Down

With Paul McCullagh’s PBXT storage engine getting integrated into MariaDB 5.1, it’s never been easier to it out. So we have, on a slave off one of our own production systems which gets lots of inserts from our Zabbix monitoring system.

That’s possibly an ideal usage profile, since PBXT is a log based engine (simplistically stated, it indexes its transaction logs, rather than rewriting data from log into index and indexing that) so it should require less disk I/O than say InnoDB. And that means it should be particularly suited to for instance logging, which …
