Aliaksandr Valialkin	adc18c3ee6	lib/{mergeset,storage}: do not cache inverted index blocks containing tag->metricIDs items ... This should reduce the amounts of used RAM during queries with filters over big number of time series.	2019-09-25 13:48:24 +03:00
Aliaksandr Valialkin	7d13c31566	lib/{storage,mergeset}: merge tag->metricID rows into tag->metricIDs rows for common tag values ... This should improve lookup performance if the same `label=value` pair exists in big number of time series. This should also reduce memory usage for mergeset data cache, since `tag->metricIDs` rows occupy less space than the original `tag->metricID` rows.	2019-09-20 22:06:23 +03:00
