Any service that wants to use memcache for the keystone authtoken caching should be configured with a single server for optimal performance when server might be unavailable. This is due to the way most python memcache libraries operate. Most put the memcache servers into a pool and if one goes down, the request will incur a connection penalty if the server is unreachable. |
Any service that wants to use memcache for the keystone authtoken caching should be configured with a single server for optimal performance when server might be unavailable. This is due to the way most python memcache libraries operate. The python-memcached hashes the key to a specific server but if that server is down it impacts every request from then on.
https://github.com/linsomniac/python-memcached/blob/master/memcache.py#L435-L453
Based on previous experience it was determined that the best all around solution was to configure a single memcached server to the authtoken caching to prevent SLA issues when memcache (or physical) servers fail. |
