Fabian Reinartz	9790aa98ac	Add postings wrapper that emits head postings in label set order ... This adds a position mapper that takes series from a head block in the order they were appended and creates a mapping representing them in order of their label sets. Write-repair of the postings list would cause very expensive writing. Hence, we keep them as they are and only apply the postition mapping at the very end, after a postings list has been sufficienctly reduced through intersections etc.	2017-01-05 16:05:42 +01:00

Fabian Reinartz	beb842a856	Change block interface ... This changes the block interface to directly expose index and series readers rather than the direct querier	2017-01-02 11:12:28 +01:00
Fabian Reinartz	5d75a3dc7b	Add basic compaction ... This adds a basic compactor that will merge two persisted blocks into one. It simply fully rewrites the index and concatenates the chunk lists. It just writes into the current working dir and doesn't properly handle which blocks to compact for now.	2017-01-02 10:34:55 +01:00
