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.

I’m pleased to announce the release of the Narada Search Engine Application, version 0.202, as well as a ready-to-use AMI, ami-140df07d.

The source release can be found at Launchpad – lp:narada and and a packaged version at http://patg.net/downloads/narada-0.202.tar.gz

What is Narada? Narada is a search engine application. It does have a web application component, but it also has a very novel approach on the back-end in how it implements various functionalities by using Gearman, memcached, Sphinx and either MySQL or Drizzle as a data store. It is somewhat of a proof-of-concept that was borne from an idea I had one late night while working on my first book, Developing Web …

Why use PBMS?

I have talked to people about why they should use PBMS to handle BLOB data often enough, so I was surprised when someone asked me where they could find this information and I discovered I had never actually written it down anywhere.  So here it is.
If you are unfamiliar with PBMS, PBMS stands for PrimeBase Media Streaming. For details please have a look at the home page for BLOB Streaming.
  Both MySQL and Drizzle are not designed to handle BLOB data efficiently. This is not a storage engine problem, most storage engines can store BLOB data reasonably efficiently, but the problem is in the server architecture itself. The problem is that the BLOB data is transferred to and from the server as part of the regular result set. To do this both the server and the client must allocate a buffer large enough to hold the entire BLOB. DBMSs …

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 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.

Xtrabackup

…

With this revision, My xtrabackup branch has been merged into trunk.

What does this mean? It means that we now get a drizzlebackup.innobase binary which is the xtrabackup port for Drizzle. Exciting times.

As Lee mentioned on the Drizzle blog, we have an upcoming Drizzle Developer Day just after the MySQL Conference and Expo. Sign up here to make sure we have enough space and can help with planning.

The last couple developer days have been great – helping people getting started with Drizzle, discussing improvements that could be made (both big and small), operations concerns and new to this one: a GA release.

Having a GA release out is really exciting, I’m hoping that on the developer day we get people …

Follow it over on launchpad.

After having fixed an incredibly odd compiler warning (and with -Werror that we build with, error) on OSX (die die die) – xtrabackup for Drizzle is ready to be merged. This will bring it into our next milestone: freemont. Over the next few weeks you should see some good tests merged in for backup and restore too.

While not final final, I’m thinking that the installed binary name will be drizzlebackup.innobase. A simple naming scheme for various backup tools that are Drizzle specific. This casually pre-empts a drizzlebackup tool that can co-ordinate all of these (like the innobackupex script).

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.
