  1. Drizzle MicroKernel

  2. In the beginning...

  3. 5.0 Customer Advisory Board

  4. Leap Forward • Further Ease of Use • Focus on the Web • Use Open Source Methodology

  5. Focus On Tomorrow • World is 64bit • SSD will be the common in Two Years • No New Locks, More Cores will be Common • Modern Applications • C++/STL/Boost

  6. Further Ease of Use

  7. One BlobNo Three Byte Integer

  8. Интернет является UTF-8. は、 Web UTF - 8です。 The Web is UTF-8.

  9. No Gotchas • No bad record inserts. • No hidden truncations. • No “is my filesystem case sensitive” issues • No Modes

  10. Infrastructure Aware

  11. Organic Open Source • Everything is public, complete transparency. • Release Early, Release Often. • Launchpad and Hudson • There is no Drizzle INC.

  12. Query 101101 Query 101101 Query Memcached Cache Parser Parser Optimizer Optimizer Client Client Client Routing Proxies Storage Routing SQL & REST

  14. Today’s Pluggable Interfaces • Replication • Storage Engine • Logging • Authentication • Authorization • Table Functions • Functions • Protocol • Query Rewrite • XA

  15. Replication • Google Protocol Buffer Based • Replicates row transformations. • Integrates today with RabbitMQ, Casandra. Memcached, Gearman

  16. libdrizzle • Supports Drizzle (and MySQL, and SQLite) • Asynchronous • BSD

  17. Authentication/Authorization • No Cost Authentication • PAM, LDAP, HTTP

  18. Table Functions • TABLE_CACHE • TABLE_DEFINITION_CACHE • SHOW TEMPORARY TABLES • All new SQL compliant information_schema

  19. Storage Engines • For nearly two years we have been a transactional database by default. • No more table level locking engines. • Federated Data Dictionary.

  20. Akiban.com • Shared Nothing • Join Cost Elimination • Cloud Ready

  21. What are the highlights?

  22. 80+ Code Contributors

  23. 4 Companies With Core Developers

  24. 41 Active Translations

  25. 109,00 Lines of Code in Kernel • (209,000)

  26. No Warnings for GCC, Sun Studio

  27. DBT2, Sysbench, SQLBench, Slap,Crash-Me

  28. ~440 goto’s • (compared to +2000)

  29. Are we there yet?

  30. Default Engine has been transactional for over a year, and passes all test cases. • Upgrades still require reload. • Replication is still under testing.

  31. Where are we going?

  32. Rackspace • Coming Beta with Cloud Sites web platform. • “Committed to Drizzle for it to succeed not only for our needs, but for the community needs.”

  33. Better user usage tracking/resource handling. • More Authentication Handlers • Hardened Replication • Shared Nothing Storage Nodes • Server Side Scripting • <YOUR WORK>

  34. Drizzle Developer Day! This Friday, room 209/210 http://drizzle.org http://planetdrizzle.org Freenode #drizzle
