SkySQL and MariaDB are very pleased to announce a new baby in the storage Engine family : The “CONNECT Storage Engine” I have had the pleasure to work with Olivier Bertrand creator of the CONNECT storage Engine. Olivier has over 50 years of experience in database development as an ex-IBM database researcher. Olivier was very [...]

Since we announced that TokuDB is now open source, there has been a lot of positive feedback (thanks!) and also some questions about the details. I want to take this opportunity to give a quick high level guide to describe what our repositories on Github are.

Here are the repositories:

• ft-index. This repository is the “magic”. It contains the Fractal Tree data structures we have been talking about for years. This is also the main piece that was previously closed source. Here are some interesting directories:
  • src: This directory is a layer that implements an API that is similar to the BDB API.
  • locktree: an in-memory data structure that maintains transactions’ row-level locks. …

2010 was a good year for implementing many small feature requests. Lets start by thanking those responsible for requesting these enhancements: Matt Lord, Mikiya Okuno, Matthew Montgomery, Mark Callaghan, Domas Mituzas and Mats Kindahl.
MySQL 5.6 has lots of big and shinny new replication features. In fact some, like global transaction identifiers or multi-threaded slave, are multiple features together under one big headline. Therefore, they get a lot of buzz and since they are complex, game-changing and very exciting to the end user, they deserve a lot of blog posts. But what about other smaller enhancements that are in 5.6 but that do not get so much highlight? 
Let me present a few that I think are particularly interesting, especially for monitoring and/or configuration purposes. To get more details, click on the links and they will take you to the feature requests or worklog entries. 1. …

At this month’s Back Bay LISA, Matt Simmons (aka Standalone Sysadmin) set up Lightning Talks. There were 9 presentations, and the videos are up! The playlist is on YouTube but here is a list of all the videos, with the descriptions taken from Matt’s blog post:

Percona Server with TokuDB

I was excited to see that TokuDB for MySQL from Tokutek is now open source. I believe this is a great technology and it was a significant restriction on the adoption when it was distributed only in a binary format with a proprietary license.

So I went and built Percona Server 5.5.30 with TokuDB’s storage engine. This is an experimental build and I am just going to play with it. The build procedure is somewhat complicated and confusing and this stage, so I want to share it with the entire MySQL community in case you want to try it out for yourselves.

It’s available from our …

This morning I watched Tomas Ulin’s Keynote at Percona Live: MySQL Conference and Expo, delivered yesterday. I missed this live as I am not at Percona Live (I am on a conference hiatus from March through September for personal reasons). As far as the technical content in it, there have been a few posts about the Hadoop Applier and MySQL 5.7, so there’s not much of a need to delve in there.

Message #1: Failure
I was impressed that Ulin spoke of failure. Around 7:27 in the video above, Ulin says, “We really failed with 5.0,” and “even 5.1 we weren’t fully and back on track when we released.” He spoke about the new way MySQL 5.5 and 5.6 were engineered, a hybrid agile/milestone development cycle. There are some hidden messages here:

Hidden Message #1: Oracle is a great steward for …

Continuing on from yesterday, the biggest news that I’ve noted in the past 24 hours:

1. The commitment from Oracle’s MySQL team to release a new GA about once every 24 months, with a Developer Milestone Release (DMR), with “GA quality” every 4-6 months. Tomas Ulin announced MySQL 5.7 DMR1 (milestone 11) [download, release notes, manual]. He also announced MySQL Cluster 7.3 DMR2 [download, …

In our last 5.5 series release of Percona Server, we included a regression in the RPM packaging that prevented the server from restarting following an upgrade — instead, the server would remain stopped after the upgrade was completed regardless of its state before updating. This caused some problems for some users, especially if automatic upgrading was configured on machines with running database servers.

We’ve now fixed it and re-released to …

I ran across this gem recently on StackOverflow:

$queryxyzzy12=("SELECT * FROM visitorcookiesbrowsing ORDER by id ASC"); $resultxyzzy23=mysql_query($queryxyzzy12) or die(mysql_error());

while($ckxf = mysql_fetch_assoc($resultxyzzy23)){ $querycrtx=("SELECT * FROM cart WHERE userkey='$ckxf[usercookie]' ORDER by datebegan DESC"); $resultcrtx=mysql_query($querycrtx) or die(mysql_error());
