3. In the beginning...

4. 2005 MySQL 5.0 with lack fanfare from Web Developers 2008 Sun buys MySQL 2008 MySQL 6.0 becomes Drizzle 2009 Oracle buys Sun 2010 Drizzle Developers split from Oracle 2011 First GA Release, Drizzle7

5. Entirely Open Source RDBMS C++, with a MicroKernel Design No Gotchas 120+ Developers since start, 24/36 active per month. The most active child of the MySQL forks. Drizzle

6. Drizzle7 (Quick Update)

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

8. HTTP Blob Streaming Client Replication Client Listener Query Memcached Cache ParserOptimizer Storage System Logging Error Reporting HTTP Client MySQL MemcachedGearman ExecutionerSQLDrizzle MicroKernel Cloud Service

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

10. INSERT INSERT UPDATE INSERT Stored Transactionall y

11. Maste r Slave Slave Slave

12. Slave Slave Slave

14. What group commit problem?

15. Transacti on Log Binlog Group Commit? DatabaseKernel

16. Transacti on Log No Group Commit Required DatabaseKernel

17. libDrizzle Supports Drizzle (and MySQL, and SQLite) Asynchronous BSD Lawyer free

18. Client Instance Amazon S3 Storage NoSQL Stream Access

19. Is there more?

20. No Gotchas No NULL when you don’t want NULL No ALTER TABLES that fake’ it Real datetime (64bit), with microseconds IPV6 No updates that “half complete”

21. Authentication/Author ization No Cost Authentication PAM, LDAP, HTTP

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

23. Data Dictionay Separate Information Schema for ANSI SQL access. All based on Table Functions No Materialization Single Execution Path

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

25. How about locks?

26. SHOW PROCESSLIST (now based on table functions)

27. --skip-grants (none of the current GRANTs require LOCKS actually…)

28. store_lock() (all engines are not created equally)

29. 120+ Developers Since Day One 26/36 on average each month

30. Drizzle 7+

31. Users Instance Schema Schema Table Table Table Table Table Table Table Table Table Table Table Table

32. Users Instance Table Table Table Users Table Table Table

33. Cuts the 30/40% hit from virtualizing Single instance maintenance Still allows for IO spread on San/NAS

34. Supports Partial Backup No locking Single solution, point-in-time recovery in a single solution. Comes with the database. Hot Backup
