Welcome to this week's edition of Last Week in Drizzle.  Unfortunately I could not write this at the Drizzle Developer Day because it is was much busier than I expected.  So this one had to wait until I landed in the UK :)

O'Reilly MySQL Conference and Expo

Last week was the MySQL Conference which at this point should probably be called the MySQL & friends or the Open Database Conference.  We had many talks, great exposure and some fantastic questions and feedback of ideas we had never thought of during the week.  I urge anyone who wasn't there to watch Brian Aker's keynote on the State of Drizzle.

On the Friday after the conference we had Drizzle Developer Day which contained people from every level, new users to some of the

Welcome to this week’s Last Week in Drizzle.  This again will be a relatively short edition as the 2011 O'Reilly MySQL Conference and Expo is next week and I'm currently packing for it!

Drizzle in Real Time Data Visualization

Many of you will have seen the awesome real time data map of Mozilla's downloads on their glow site.  One thing that got me really excited this week was work by Marcus Eriksson to do the same thing using Drizzle and it's RabbitMQ connector.  The live demo of this has been hosted on a Rackspace cloud server and can be found here.

Welcome to this week's Last Week in Drizzle.  Today will be a relatively short edition due to the work everyone is doing preparing for the 2011 O'Reilly MySQL Conference and Expo and Google Summer of Code.

First Fremont Tarball

The first tarball of the Fremont development branch of Drizzle was created this week, following our tradition of releasing a tarball every two weeks.  It includes many experimental things such as the libdrizzle-2.0 separation and the multiple master to single slave replication.

For those wanting the stable release we suggest sticking to the Elliott branch which our GA was cut from.  New releases for this will be created much less frequently and will only include bug fixes.

Welcome to this week's (slightly late) edition of Last Week in Drizzle.  This week sees the kick-off of many new features for the next release of Drizzle codenamed 'Fremont' and the mailing list is a hive of activity around Google Summer of Code.  I apologise for publishing a few days late this week and will try and stay on-track for future editions.

Fremont

In the tradition of Drizzle using Seattle road names in alphabetical order for codenames the next release of Drizzle is codenamed 'Fremont' (the current GA release is codenamed 'Elliott').  Monty Taylor has outlined the merge process going forward as can be seen in his mailing list post.

Welcome to the latest edition of Last Week in Drizzle.  This week we announced our GA release!!  Interest in Drizzle in the last week has been much higher than anticipated, this blog alone got 4,500 visitors on Wednesday! (which was also a nice test for the Drizzle database powering it)

GA Release

So, on Tuesday the tarball was cut for our GA release called Drizzle7.  Most of the changes from the last week relate to code cleanup, documentation and test suite improvements so that we could keep the codebase stable ready for the release (also many of us are busy writing conference talks around now ).  For a quick summary of what to expect in Drizzle7 and the future you can see my three-part special called “Drizzle – The Icing on the Cake”: part 1

Welcome to this week’s edition of “Last Week in Drizzle”.  As an introduction this week I would like to quote John David Duncan’s recent Facebook post: “And what’s in the weather forecast for next week? Drizzle.”.  Yes, our first GA release is due next week, does that mean the development pace has slowed?  Heck no!  Over 150,000 lines of bzr diff in the trunk since last week and quite a few branches still in the merge queue going through our extensive regression testing system.

Google Summer of Code

We have once again applied to be part of the Google Summer of Code program.  We had some great students last year and some new faces interested in being students on projects for Drizzle have already started taking on some low-hanging-fruit tasks to get them used to our code and processes.  We will have a sign-up form up soon so that anyone interested in

Welcome to the third edition of Last Week in Drizzle.  The diff of the trunk between last Friday and right now is just over 230,000 lines in size, 10x the size of the previous week!  This includes many changes to the documentation, code clean-ups and Patrick Crews’ continued work on our new DBQP test suite.

Replication

David Shrewsbury (I’m going to spell his name correctly this week ) and Patrick Crews have been working hard on making replication even more rock solid.  The slave plugin is in, working and is stable with everything we can throw at it.

Welcome to the second edition of Last Week in Drizzle.  The diff of the trunk between last Friday and right now is just under 23,000 lines in size, so I will do my best to summarise the important parts of this.

Replication

A lot of great work has gone into solidifying replication this week.  The slave code has not been merged yet since it has been triggering bugs in the Solaris compiler (see further down this post) but we plan to have it included in the next few hours ready for RC2.  For a quick summary of our current progress I turn to Patrick Crews:

"In our testing, we create a master-slave setup, then run the transaction log tests that we have been using since we first started beating on the trx log.

There are a variety of different grammars that produce transactions

It has been a while since we have done one of these so I thought I might try and resurrect the tradition.  So here is my first "Last Week in Drizzle".

Replication

The original plan for replication was to use a Tungsten Replicator based solution to transfer the transaction logs (similar to MySQL's binary logs).  Unfortunately this can't be completed in time for the GA release so we have switched to a master-slave solution similar to MySQL.  The Tungsten solution is still something we plan to finish though.

Replication events are stored using Google Protocol Buffer messages in an InnoDB table, these events are read by the slave, stored locally and applied.  The advantage of the Google Protocol Buffer messages is a script or program can be
