Description RHOS Integration 2014-07-22 04:11:02 UTC
Cloned from launchpad blueprint https://blueprints.launchpad.net/oslo/+spec/switch-to-mysql-connector.


Current MySQL client library we use (MySQLdb) plays bad with eventlet and may result in db deadlocks [1]. It also blocks execution of other green threads while we're deep in the library code [2]. To avoid those issues, we need to switch to a pure python library with better eventlet support. MySQL Connector is an official mysql python client library and has the needed qualities.
