Openshift resource limit and pagecache -


i'm running kafka cluster on openshift. understand, kafka performance relies on pagecache. trying understand how best can limit resource on kafka container works efficiently.

linux tries use available ram buffer speed disk operations. assuming there kafka container running on node, if set limit on container 5gi, rest of available memory on node used buffer/cache believe.

i wondering if set limit 10gi , if kafka use 5gb, remaining unused 5gb still available pagecahce operating system?

the limit doesn't reserve memory, puts cap on how application can use. don't believe should affect how operating system handles kernel buffer/cache.
