Aliaksandr Valialkin	44fa8226df	lib/uint64set: remove superflouos check for item existence before deleting it in Set.Subtract	2019-11-09 14:01:24 +02:00
Aliaksandr Valialkin	0063c857f5	lib/storage: add inmemory inverted index for the last hour ... It should improve performance for `last N hours` dashboards with update intervals smaller than 1 hour.	2019-11-08 19:37:46 +02:00
Aliaksandr Valialkin	f5fbc3ffd7	lib/{storage,uint64set}: add Set.Union() function and use it	2019-11-04 00:48:32 +02:00
Aliaksandr Valialkin	44fab198e2	lib/uint64set: return an emptry set instead of nil set from Set.Clone, since the caller may add data to the cloned set ... This fixes the following panic in v1.28.1: panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x1 addr=0x10 pc=0x783a7e] goroutine 1155 [running]: github.com/VictoriaMetrics/VictoriaMetrics/lib/uint64set.(*Set).Add(0x0, 0x15b3bfb41e8b71ec) github.com/VictoriaMetrics/VictoriaMetrics@/lib/uint64set/uint64set.go:57 +0x2e github.com/VictoriaMetrics/VictoriaMetrics/lib/storage.(*indexSearch).getMetricIDsForRecentHours(0xc5bdc0dd40, 0x16e273f6b50, 0x16e2745d3f0, 0x5b8d95, 0x10, 0x4a2f51, 0xaa01000000000000) github.com/VictoriaMetrics/VictoriaMetrics@/lib/storage/index_db.go:1951 +0x260 github.com/VictoriaMetrics/VictoriaMetrics/lib/storage.(*indexSearch).getMetricIDsForTimeRange(0xc5bdc0dd40, 0x16e273f6b50, 0x16e2745d3f0, 0x5b8d95, 0x10, 0xb296c0, 0xc00009cd80, 0x9bc640)	2019-11-01 16:12:21 +02:00
Aliaksandr Valialkin	c64fb91a43	lib/uint64set: optimize Set.AppendTo	2019-09-25 00:34:31 +03:00
Aliaksandr Valialkin	de0e4eee2c	lib/storage: create and use lib/uint64set instead of map[uint64]struct{} ... This should improve inverted index search performance for filters matching big number of time series, since `lib/uint64set.Set` is faster than `map[uint64]struct{}` for both `Add` and `Has` calls. See the corresponding benchmarks in `lib/uint64set`.	2019-09-24 21:18:04 +03:00
