Aliaksandr Valialkin	a9525da8a4	lib: consistently use f-tests instead of table-driven tests ... This makes easier to read and debug these tests. This also reduces test lines count by 15% from 3K to 2.5K See https://itnext.io/f-tests-as-a-replacement-for-table-driven-tests-in-go-8814a8b19e9e While at it, consistently use t.Fatal* instead of t.Error*, since t.Error* usually leads to more complicated and fragile tests, while it doesn't bring any practical benefits over t.Fatal*.	2024-07-09 22:40:50 +02:00
Aliaksandr Valialkin	f325410c26	lib/promscrape: optimize service discovery speed ... - Return meta-labels for the discovered targets via promutils.Labels instead of map[string]string. This improves the speed of generating meta-labels for discovered targets by up to 5x. - Remove memory allocations in hot paths during ScrapeWork generation. The ScrapeWork contains scrape settings for a single discovered target. This improves the service discovery speed by up to 2x.	2022-11-29 21:26:00 -08:00
