What are general community guidelines on setting up C* heap size, file_cache_size_in_mb, offheap space usage and other RAM usage settings?
Are there any general guidelines like "if your total data size per node is X/median/max partition size is Y, your RAM usage settings better be Z or things will be kinda slow"? If no - are there any ways to deduce such values other than trial-and-error? Our case: 2.4 tb/node, median partition size 340mb, max partition size 2Gb, and we can't concider partition schema changes. Thank you.
