Aliaksandr Valialkin	c25b839078	lib/workingsetcache: reset the cache mode when the cache is reset ... This should reduce memory usage if the working set is reduced after the cache reset.	2021-07-01 11:50:11 +03:00
Aliaksandr Valialkin	4146fc4668	all: properly handle CPU limits set on the host system/container ... This can reduce memory usage on systems with enabled CPU limits. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/946	2020-12-08 21:07:29 +02:00
Aliaksandr Valialkin	0681b4c27a	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 11:51:40 +03:00
Aliaksandr Valialkin	48999e5396	lib/workingsetcache: remove data race when resetting c.misses	2019-09-22 19:36:49 +03:00
hanzai	e2274714b1	lib/workingsetcache: adjust switching from mode=split to mode=whole smoothly and load cachefile successfully	2019-09-13 19:13:01 +03:00
Aliaksandr Valialkin	483de1cc06	lib/workingsetcache: automatically detect when it is better to double cache capacity	2019-08-15 22:57:55 +03:00
Aliaksandr Valialkin	09fc6e22e5	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 21:39:34 +03:00
