Description RHOS Integration 2013-12-12 19:26:19 UTC

Cloned from launchpad blueprint https://blueprints.launchpad.net/glance/+spec/mysql-thread-pool.

Description:

Add eventlet db_pool use for mysql

This adds the use of eventlet's db_pool module so that we can make mysql
calls without blocking the whole process.

New config options introduced are:

use_tpool -- Enables the use of eventlet's db_pool
backend - The backend to be used for DB

The default for use_tpool is False , so there is
no forced behavior changes for those using mysql.
