Aliaksandr Valialkin	f0b08dbd9e	lib/workingsetcache: accumulate stat counters on cache rotation ... This should prevent from cache stats counters going down after cache rotation, which may corrupt `cache hit ratio` graph on the official Grafan dasbhoards when using the following query: 1 - (sum(rate(vm_cache_misses_total[5m])) by (type) / sum(rate(vm_cache_requests_total[5m])) by (type))	2020-04-10 11:51:47 +03:00

Aliaksandr Valialkin	8c2158af24	all: use workingsetcache instead of fastcache ... This should reduce the amount of RAM required for processing time series with non-zero churn rate. The previous cache behavior can be restored with `-cache.oldBehavior` command-line flag.	2019-08-13 21:40:28 +03:00
