661b8ede5b lib/storage: harden the check that the original items are sorted after mergeTagToMetricIDsRows fails to preserve sort order 2019-10-09 12:13:43 +03:00
Aliaksandr Valialkin
7e410e1412 lib/storage: add tests for mergeTagToMetricIDsRows and return the original items if the function breaks items` ordering. 
This should save from data corruption issues revealed in the previous releases up to v1.28.0-beta5.

95e3d648cb lib/storage: verify whether items are sorted in the end of call to mergeTagToMetricIDsRows 
This should prevent from inverted index corruption if bug in mergeTagToMetricIDsRows is discovered.

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

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.

f1d81b9405 lib/storage: compress contents of cache for tagFilters -> TSIDs 
This should increase cache capacity

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.

362e187011 lib/storage: use unversioned keys for tag cache in extDB 
Data in ExtDB cannot be changed, so it is OK to use unversioned keys for tag cache.
This should improve performance for index lookups over big amount of time series.

51e2f3b48f lib/storage: skip searching in extDB if it doesn't contain items for the given time range 
This should improve inverted index search performance for big amount
of unique time series when the search is performed only on recent data.

d54f5fec0b lib/storage: skip adaptive searching for tag filter matching the minimum number of metrics if the identical previous search didn't found such filter
