Drizzle source tarball based on build 1273 has been released. This marks completion of our Bell milestone. We made a lot of great progress and improvements during the Bell milestone, one of the main goals was to make sure data loss does not occur so that active testing can now occur. While Bell has been completed, upgrading will continue to require dump/load , so hopefully we will nail that down soon and let you know when it is ready.
Stay tuned for more information on goals and features for the our next major milestone which will be code named Cherry.

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!

For Drizzle build 1240 this release includes:
Dynamic loading of plugins at server start up
- The majority of the existing plugins have been set to be loaded dynamically rather than compiled statically with the server
- Non-default plugin modules can be loaded with a command line option, —plugin-add, which takes a comma-separated list of plugin module names, e.g.: —plugin-add=csv,memcached_functions
- —plugin-add will load the default list of plugins in addition to the plugins requested
- —plugin-load which takes a similar list but overrides the entire list of plugins to be loaded
- In the source tree plugin test cases are now kept with the plugins themselves, so a provided plugin can be self-contained and also provide test cases
HEAP has been renamed to MEMORY when specifying the storage engine
