Re: [openstack-dev] [sahara] migration to olso.db

2014-08-18 Thread Sergey Lukjanov
Hey Ionely,

the oslo.db is a graduated version of code from the oslo-incubator
(that was periodically synced to sahara.openstack.common.db). So, the
only reason is to switch to the graduated lib.

Re: [openstack-dev] [sahara] migration to olso.db

2014-08-18 Thread lonely Feb
By the way, i created a test case that multi-user query sahara by api at
the same time. I found that the qps is about 10-20. I can see when a db
query occured the eventlet switch to another keystoneclient thread and
switch back about 1 seconds, so the query qps is quite low. I wonder is
that the performance bottleneck of eventlet + mysqldb ?
