Aliaksandr Valialkin	ab4f090c63	lib/promscrape/discovery/kubernetes: reduce memory usage further when big number of scrape jobs are configured for the same kubernetes_sd_config role ... Serialize reloading per-role objects, so they don't occupy too much memory when objects for many scrape jobs are simultaneously refreshed. Do not reload per-role objects if they were already refreshed by concurrent goroutines. This should reduce load on Kubernetes API server when big number of scrape jobs are configured for the same Kubernetes role.

Aliaksandr Valialkin	17b87725ed	lib/promscrape/discovery/kubernetes: reduce memory usage when Kubernetes service discovery is configured on a big number of scrape jobs ... Previously vmagent was creating a separate Kubernetes object cache per each scrape job. This could result in increased memory usage when monitoring a Kubernetes cluster with big number of objects (pods / nodes / services, etc.) as seen at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1113 Now it uses a shared map of scrape objects across multiple scrape jobs.	2021-03-05 17:29:55 +02:00

Aliaksandr Valialkin	388cdb1980	lib/storage: do not re-calculate stats for heavy tag filters ... This should reduce the number of slow queries when stats for heavy tag filters was recalculated.	2021-02-21 21:39:01 +02:00
Aliaksandr Valialkin	48656dcc38	lib/{mergeset,storage}: allow merging smaller number of small parts ... While this may increase CPU and disk IO usage needed for background merge, this also recudes CPU usage during queries in production. This is because such queries tend to read recently added data and it is better to have lower number of parts for such data in order to reduce CPU usage. This partially reverts ebf8da3730	2021-02-21 21:28:36 +02:00

Aliaksandr Valialkin	711f8a5b8d	lib/storage: sort tag filters by the number of loops they need for the execution ... This metric should work better than the filter execution duration, since it cannot be distorted by concurrently running queries.	2021-02-18 12:47:38 +02:00
Aliaksandr Valialkin	ce99b48a9a	Revert "lib/mergeset: tune lifetime for entries inside block caches" ... This reverts commit 458c89324d. Production testing revealed zero improvements for memory usage with reduced lifetime for entries in block caches.	2021-02-17 20:42:21 +02:00

Aliaksandr Valialkin	faad6f84a4	lib/storage: return back filter arg to getMetricIDsForTagFilter function ... The filter arg has been removed in the commit c7ee2fabb8 because it was preventing from caching the number of matching time series per each tf. Now the cache contains duration for tf execution, so the filter shouldn't break such caching.	2021-02-17 19:33:22 +02:00

Aliaksandr Valialkin	c727d2219b	lib/storage: properly hanle regexp tag filters with dots, which can be converted to full string match filters. ...

Previously targets with big number of metrics and/or labels could generated too big buffers, which then could be re-used when scraping targets with small number of metrics. This resulted in memory waste. Now big buffers are used only for targets with big number of metrics / labels, while small buffers are used for targets with small number of metrics / labels.	2020-08-16 22:29:51 +03:00
Aliaksandr Valialkin	d6967319b6	lib/leveledbytebufferpool: allocate byte buffers with capacity rounded to the upper boundary for the given bucket ... This should reduce the number of resizings for the returned byte buffers.	2020-08-16 22:13:30 +03:00
Roman Khavronenko	f5f59896ec	lib/decimal: rename significant decimal digits to significant figures (#698) ... The previous notion was inconsistent with what `decimal.Round` does. According to [wiki](https://en.wikipedia.org/wiki/Significant_figures) rounding applied to all significant figures, not just decimal ones.	2020-08-16 17:21:35 +03:00
