4468f9f966 lib/storage: remove duplicate MetricIDs in tag->metricIDs items before writing them into inverted index 2019-09-25 17:57:36 +03:00
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.

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`.

9307de1b92 lib/storage: limit the number of metricIDs in tag->metricIDs row 
This reduces the overhead on index and metaindex in lib/mergeset

7734fc8012 lib/storage: share tsids across all the partSearch instances 
This should reduce memory usage when big number of time series matches the given query.

67a2bcb98a lib/{storage,mergeset}: verify PrepareBlock callback results 
Do not touch the first and the last item passed to PrepareBlock
in order to preserve sort order of mergeset blocks.

d2ed8cb0b2 lib/storage: generate the first tag->metricIDs item in a mergeset block with a single metricID 
The first item from each mergeset block goes into index (lib/mergeset.blockHeader),
so it must be short in order to reduce index size.

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.

7e0c6d4ca6 lib/storage: optimize selecting all the metricIDs by scanning MetricID->TSID entries instead of tag->MetricID entries 
The number of MetricID->TSID entries is smaller than the number of tag->MetricID entries
and MetricID->TSID entries are usually shorter than tag->MetricID entries.
This should improve performance when selecting all the metricIDs.

947decb3dd lib/storage: remove outdated comment on maxRowsPerSmallPart 
The commend became outdated after the commit ed6ac1a5df027f0dfc22448e3b27c26b6f77c67a,
which stops merging of small parts on graceful shutdown instead of waiting
for their completion.

8c2158af24 all: use workingsetcache instead of fastcache 
This should reduce the amount of RAM required for processing time series
with non-zero churn rate.

The previous cache behavior can be restored with `-cache.oldBehavior` command-line flag.
