2. What is HailDB? 3. What is InnoDB? 4. ACID database enigne 5. Commonly found in MySQL 6. Originally was separate 7. Been in MySQL forever 8. HailDB and InnoDB have... 9. Features you'd expect 10. Exposed through SQL 11. Really an interface to an InnoDB API 12. InnoDB internal API 13. Complex and sometimes MySQL specific 14. HailDB history 15. Embedded InnoDB 16. A couple of releases... 17. Abandoned? 18. Enter HailDB 19. Completely free and open source project 20. http://www.haildb.com 21. Launchpad 22. $ bzr branch lp:haildb 23. Tarball releases 24. Packaged in Ubuntu Natty 25. Packaged in drizzle-developers PPA 26. Also RPMs 27. (Currently) no Win32 release 28. Source compatible with embedded_innodb 29. libhaildb.so 30. haildb.h 31. Pandora-build provides autoconf foo 32.
