Increase size for cache

Google Cloud Apigee

Hello All,

I have a populate cache. For every request, I need to cache the sessionid and cookie value.

Timeout is 1 day, since we are not sure about the exact timeout of sessonid. Our TPS is 10. so per day my cache will have 864000. But my cache settings are below. I f i want to maintain above data? how to configure the proxy and how to scale the CPU, MEMORY of RMP and cassandra.

Regards,

Ch.Venkat.

Hi @venkat ch,

This depends on the size of entry. There are restrictions on the size of cache and detail can be found here.

I would suggest to optimize TTL (as 1 day) by analysing the Cache hit-ratio. Also, to reduce negative impact of consuming too much memory via cache, internal logic of cache to move keys to disk space by using least-recently-used algorithm.
