impact of extensive caching - OPDK

[sjm2000]

Dear Team,

Currently one customer is requesting extensive caching for 20 days . We have standard 13 node OPDK installation of version 19.06 .

I presume additional caching will have more some server resource utilization. However , which component would would have biggest impact in OPDK for extensive caching.

Ex. Cassandra / Postgres / MP?

Thanks & Regards

This will have more impact on Message processor. You can use external caching systems for that.

MP/Cassandra will have higher load, Please size your MP and C* appropriately, including the cache expiry

Thank you

Can you be a little more specific ?

- is it load on memory or cpu or disk i/o ?(for MP and Cassandra)

This is load on memory.
