What are the highlights?

80+ Code Contributors

4 Companies With Core Developers

41 Active Translations

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

No Warnings for GCC, Sun Studio

DBT2, Sysbench, SQLBench, Slap,Crash-Me

~440 goto’s (compared to +2000)

Are we there yet?

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

Where are we going?
