Drizzle

Thanks to Eric and Padraig, Drizzle has been accepted as its own project for Google’s Summer of Code 2010. See Padraig’s blog for more details. Any students who are interested in working on Drizzle should check out our ideas page on our wiki.

Check out the recent Rackspace blog and video from Rackspace System Architect Adrian Otto announcing the Drizzle team.

We finally have our location for Drizzle Developer Day 2010, this year it will be at the Santa Clara Convention Center, rooms 209 and 210. As we previously announced the event will be Friday April 16th right after the MySQL User Conference, 9:30 a.m. to 5:00 p.m.

Please make sure and sign up at http://drizzle.org/wiki/Drizzle_Developer_Day_2010_signup. Space will be limited and it is filling up fast.

Also, to make this day a success, please provide your input on discussion topics at http://drizzle.org/wiki/Drizzle_Developer_Day_2010

Hope to see you there!

A lot of you have been wondering where the Drizzle developers who were working at Sun have landed after the Oracle acquisition. As I’m sure you have seen by now we are very happy to now be working on Drizzle at Rackspace Cloud. Check out the blogs from Eric, Jay, Monty and Stewart.

Check out Brian’s blog which details all the features we are targeting for our next release, code name Cherry. Actually in launchpad these are termed “series” and within each series we are defining two week milestones to track our progress. Currently looking to complete Cherry by the end of April.

We are very happy to announce Drizzle Developer Day is coming again this year. Similar to last year it will be the Friday after the MySQL users conference, April 16 – 9:30 a.m. to 5:00 p.m. We are still working on the exact location and will let you know as soon as possible, most likely it will be at or very close to the Santa Clara convention center. We invite anyone interested in providing feedback, implementing new features, helping to fix bugs, or just wanting to learn more about Drizzle to attend.

We recently added support for running the dbt2 benchmark as part of our drizzle automation suite. dbt2 is an OLTP transactional performance test. It simulates a wholesale parts supplier where several workers access a database, update customer information and check on parts inventories. We currently are using the defaults (10 warehouses, 5 minute test runs and running various number of connections for each run up to 1024. The initial runs exposed a race condition in our TemporalFormat::match() code at 1024 connections.

We now have a very nice suite of tools to help us with tracking performance and scalability of Drizzle, besides dbt2 we also are running sysbench, sqlbench, crash-me and randgen for all of our builds in the staging branch of Drizzle. Of course we are always looking for more, so if you have any suggestions on other benchmarks or tools to add, please let us know.

If you want to receive all of the various benchmark results you can subscribe to the mailing list.

Note also we are in the process of getting our changes to dbt2 merged to the dbt2 trunk, it should be there very soon.

Happy New Year to all!

Lots of great updates from Jay on his recent Replication work, make sure and take a look and provide feedback.
