Fabian Reinartz	c32a94d409	Unexport HeadBlock, export Block interface	8 years ago
Fabian Reinartz	4c4e0c614e	Simplify position mapper updating	8 years ago
Fabian Reinartz	8c31c6e934	Make concurrent head chunk reads safe, fix misc races ... This adds a 4 sample buffer to every head chunk. The XOR compression scheme may edit bytes in place. The minimum size of a sample is 2 bits. So keeping the last 4 samples in an in-memory buffer makes it safe to query the preceeding ones while samples are added	8 years ago
Fabian Reinartz	63e12807da	Don't update head postings mapper on every append	8 years ago
Fabian Reinartz	96c2bd249f	Handle compaction trigger and reinitializing in DB	8 years ago
Fabian Reinartz	3ed2c2a14b	Rename Partition to regular DB, DB to PartitionedDB	8 years ago
Fabian Reinartz	4590b61343	Rename shard to partition	8 years ago
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.	8 years ago
Fabian Reinartz	40cf215fba	Hotfix missing sorting of head block series index	8 years ago
Fabian Reinartz	ec99f99d3d	Fix and test bug in shardSeriesSet	8 years ago
Fabian Reinartz	62b8ded0a5	Rename iterator value getters to At()	8 years ago
Fabian Reinartz	5c45a1cc6f	Remove shardSeriesSet caching	8 years ago
Fabian Reinartz	beb842a856	Change block interface ... This changes the block interface to directly expose index and series readers rather than the direct querier	8 years ago
Fabian Reinartz	c00d17e691	Modify IndexReader API to accomodate compaction ... This changes the IndexReader API to expose plain labels and chunk meta information instead of a Series interface. Dropping of irrelevant chunks is moved into the querier. A LabelIndices method is added to query for existing label value indices.	8 years ago

Fabian Reinartz	282d9ae6e2	Implement label value queries in all layers.	8 years ago
Fabian Reinartz	aabb21f4b9	Add shard series set test	8 years ago
Fabian Reinartz	b08f82fa4e	Pre-select relevant chunks on series access. ... This adds interval metadata to indexed chunks. The queried interval is used to filter chunks when queried from the index to save unnecessary accesses of the chunks file. This is especially relevant for series that come and go often and larger files.	8 years ago
Fabian Reinartz	bd77103a49	Add stats serialization, load querier of all blocks	8 years ago

Fabian Reinartz	c1acd3fe85	Advance buffered iterator correctly on seek	8 years ago
Fabian Reinartz	e561c91d53	Implement proper buffered iterator ... This adds a proper duration based lookback buffer for series iterators to allow advancing sequentially while remaining able to calculate time aggregating functions such as `rate` backwards. It uses an array ring buffer to minimize heap allocations for potentially hundreds of thousands of series for a single query.	8 years ago
