Configure keystonemiddleware to deal with memcached pods failures #663

Commits on Nov 29, 2024

  1. Configure keystonemiddleware to deal with memcached pods failures

    Whenever one of the mecached pods disappears, because of a rolling
    restart during a minor update or as result of a failure, APIs can
    take a long time to detect that the pod went away and keep trying
    to reconnect.
    
    From a quick round of tests we saw downtimes up to ~150s.
    
    By tuning memcache_pool_dead_retry and memcache_pool_conn_get_timeout
    the behavior seems much more acceptable.
