we are using 0.13 kong and cassandra in kubernetes.
we have performed a load test on kong with db_cache_ttl set to 1800 sec ( 30 mins) . we see few calls were having high proxy latency.
After changing db_cache_ttl to 3600sec the load test was passed.
what is the use of db_cache_ttl and how it works for kong. After the cache expires what kong will load into the memory( all the cassandra data/ only per api’s as per the request).
what is the use of mem_cache_size. what is the best value to set for both the parameters for production environment for good response time.
