Aliaksandr Valialkin	ca259864e2	lib/storage: return back inmemory inverted index for recent hour ... Issues fixed: - Slow startup times. Now the index is loaded from cache during start. - High memory usage related to superflouos index copies every 10 seconds.	2019-11-13 13:11:04 +02:00
Aliaksandr Valialkin	d888b21657	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 21:21:07 +02:00
Aliaksandr Valialkin	6be4456d88	lib/{storage,uint64set}: add Set.Union() function and use it	2019-11-04 00:44:37 +02:00
Aliaksandr Valialkin	2cb811b42f	lib/uint64set: optimize Set.AppendTo	2019-09-25 00:34:17 +03:00
Aliaksandr Valialkin	b986516fbe	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 21:17:55 +03:00
