    Monday, October 12th, 2009

    Drizzle source tarball based on build 1178 has been released. While not new for this release I wanted to make sure and point out Stewart’s great tool (table_raw_reader) which reads table proto information from disk and provides a very thorough analysis of the data. Check out his blog for more details. Also in this release are

  • Updates for table definitions (removal of historic Unireg FRM bits).
  • Updates for replicationr reader
  • Bug fixes from Diego Medina
  • Updated Gearman functions
  • Addition of new sleep() function via plugin
  • Fixes for building on Snow Leaopard
  • Remove parser storage engine dependency
  • Added “CREATE TABLE A LIKE B ENGINE=engine” See Brian’s blog for more details
  • Shrunk parser structure size by half
  • Added Memcached information schema tables (you can now see the state of your memcached cluster)

    • The download file and change log can be found here.

    Random Query Generator added to Drizzle Automation

    Friday, October 9th, 2009

    We now have the Random Query Generator running as part of our automated testing framework! Thanks to Stewart for kick starting the port for Drizzle and Philip Stoev and Bernt Johnsen of the MySQL team for merging in our changes. I’m still trying to figure out all the bells and whistles and fine tuning but we have several canned configurations running and even found a bug in Drizzle as a result of some of the tests. You can see the results on the Drizzle dashboard. I welcome any feedback or suggestions for improving the setup.
