Aliaksandr Valialkin	9f94c295ab	all: use os.{Read|Write}File instead of ioutil.{Read|Write}File ... The ioutil.{Read|Write}File is deprecated since Go1.16 - see https://tip.golang.org/doc/go1.16#ioutil VictoriaMetrics needs at least Go1.18, so it is safe to remove ioutil usage from source code. This is a follow-up for 02ca2342ab	2022-08-21 23:52:35 +03:00
Aliaksandr Valialkin	f765985947	lib/fs: replace fs.OpenReaderAt with fs.MustOpenReaderAt ... All the callers for fs.OpenReaderAt expect that the file will be opened. So it is better to log fatal error inside fs.MustOpenReaderAt instead of leaving this to the caller.	2020-11-23 09:57:21 +02:00
Aliaksandr Valialkin	d120197676	lib/fs: optimize queries that read recent samples for big number of time series ... Use standard copy() func instead of mmap-aware copy func for reading recently touched mmap-ed data. This improves read performance by up to 4x.	2020-06-05 19:10:04 +03:00
