Pythian Group

This presentation was done by Sheeri Cabral of The Pythian Group and went into how to use SHOW ENGINE INNODB STATUS to get more information about your Innodb tables, foreign keys and transactions. This is a great presentation to learn how InnoDB works.

It also went through how to use SHOW ENGINE INNODB STATUS to tune several InnoDB variables:

innodb_adaptive_hash_index
innodb_commit_concurrency
innodb_concurrency_tickets
innodb_file_io_threads
innodb_log_buffer_size
innodb_max_purge_lag
innodb_sync_spin_loops
innodb_thread_concurrency
innodb_thread_sleep_delay

The slides can be downloaded from:

(Note that the slides open up to the middle section, which has slides plus notes, but if you just want the slides without notes, that starts on page 1 of the PDF.)

On Monday, October 12, 2009* from 7-9 pm at MIT, I will be giving a presentation explaining SHOW ENGINE INNODB STATUS for the Boston MySQL User Group. There is information about foreign keys, transactions, deadlocks and mutexes just waiting to be discovered, and I will show how to decipher the information.

For all those in the Boston area, I hope to see you there! For those who cannot be there, we will video this presentation and make it available online, and post here when the video/slides are up.
