Hello,
I am looking to improve the database load distribution and one of the things that may help with this is to spread out the reads. >From the configuration reference it looks like neutron dues support a >slave_connection parameter but when I enabled it and enabled query logging on >the secondary databases there aren't any queries being executed on the >secondaries. Is there anything I am missing ? Sorry for CC'ing the dev list as well but someone in the dev teams may have an answer from a developer point of view. My setup is like this: Openstack stable/mitaka (built from git) 3 galera nodes 1 haproxy running on each node with active/backup with local node as single active configuration for the frontend listening on :3306 and active/backup with the other nodes as active for the frontend listening on :3308 In neutron.conf in the [database] section I set up the the connection and slave_connection parameters like this: [database] connection = mysql+pymysql://neutron:[email protected]:3306/neutron?charset=utf8 slave_connection = mysql+pymysql://neutron: [email protected]:3308/neutron?charset=utf8 idle_timeout = 1800 max_retries = -1 retry_interval = 5 min_pool_size = 8 max_pool_size = 32 max_overflow = 16 Loooking on a slave it opens a single connection which is eventually closed because of lack of activity.
