5c2099ecfe lib/storage: return back finalPartsToMerge from 2 to 3 in order to prevent from excessive merges in old partitions 2019-11-05 17:27:48 +02:00

c62399eb3e lib/{storage,mergeset}: create missing partition directories after restoring from backups 
Backup tools could skip empty directories. So re-create such directories on the first run.

26d570bb3a lib/storage: get parts to merge after applying the limit on the number of concurrent merges 
This should reduce write amplification under high ingestion rate.

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`.

0686ac52c3 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.

1402a6b981 lib/storage: properly limit the number of output rows in small and big parts storage 
Previously small parts storage didn't take into account the available disk space for big parts.

3308279c4e lib/storage: remove outdated comment on maxRowsPerSmallPart 
The commend became outdated after the commit ed6ac1a5df027f0dfc22448e3b27c26b6f77c67a,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.

5d8d110010 lib/fs: atomically create file with the given contents on WriteFileAtomically 
This should prevent from `transaction` and `metadata.json` files corruption
on unclean shutdown such as OOM, `kill -9`, power loss, etc.
