Goutham Veeramachaneni	7bbbd55aad	Fix bug where having one chunk can cause panic ... When we have only one chunk that is out of range, then we are returning it unpopulated (w/o calling `Chunk(ref)`). This would cause a panic downstream. Fixes: prometheus/prometheus#2629 Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in>	8 years ago

Goutham Veeramachaneni	6169c33fb8	Fix #59 ... Mutating the chunks can change their length. Hence referencing using previous indices can cause panics. Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in>	8 years ago
Fabian Reinartz	a5322c50fc	Merge pull request #36 from Gouthamve/tests ... Tests For Querier and Postings	8 years ago

Goutham Veeramachaneni	b60c2068bc	Make blockQuerier return data in valid time-range ... Fixes #43 Added mint, maxt to chunkSeriesIterator. Adding a field there is inevitable as something similar is required for ignoring deleted time-ranges. Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in>	8 years ago
Fabian Reinartz	778103b450	Add liecence file and headers	8 years ago

Fabian Reinartz	7de2217011	Add fast-path for equality matching	8 years ago
Fabian Reinartz	10c7c9acbe	Adjust import names to new repository organisation	8 years ago
Fabian Reinartz	767b88a3a5	Parallelize commits to prevent deadlocks ... This parallelizes commits to prevent deadlocks across inconsistently locked heads. As commits are currently not fully atomic across heads, this does decrease our guarantees.	8 years ago
Fabian Reinartz	3be4ef94ce	Move BufferedSeriesIterator in own package ... This functionality is useful for a lot of clients but not relevant to the TSDB's core features.	8 years ago
Fabian Reinartz	a4be181d3c	Merge branch 'master' into lint-vet	8 years ago
Fabian Reinartz	2c999836fb	Add Queryable interface to Block ... This adds the Queryable interface to the Block interface. Head and persisted blocks now implement their own Querier() method and thus isolate customization (e.g. remapPostings) more cleanly.	8 years ago
Goutham Veeramachaneni	761e4768f3	Lint and Vet Fixes	8 years ago
Fabian Reinartz	65b846ae5b	Remove unreturned locks, detect writes on closed heads	8 years ago
Fabian Reinartz	a8e8903350	Use ChunkMeta references for clarity ... This has been a common source of hard to debug issues. Its a premature and unbenchmarked optimization and semantically, we want ChunkMetas to be references in all changed cases.	8 years ago
Fabian Reinartz	d6fb6aaaa8	Rename paritionSeriesSet to mergedSeriesSet	8 years ago
Fabian Reinartz	2841499212	Simplify and split up iterators ... This simplifies some of the iterators by loading chunks from the ChunkReader earlier, filtering of chunks vs filtering or series is split into separate iterators for easier testing	8 years ago
Fabian Reinartz	87805fb83f	Remove Partitioned* code	8 years ago
Fabian Reinartz	55a9b5428a	Add separate head mutex ... Introduce a seperate mutex for the head blocks to avoid a race where a post-compaction reload may run between switching the DB's base mutex to create a new head block in an appender.	8 years ago
Fabian Reinartz	78780cd2ba	Segment chunk file ... This adds write path support for segmented chunk data files. Files of 512MB are pre-allocated and written to. If the file size is exceeded, the next file is started. On completion, files are truncated to their final size.	8 years ago
Fabian Reinartz	a3d042b54e	Support multiple chunk files in read path	8 years ago
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	a009247ab7	Add matching of empty label	8 years ago
Fabian Reinartz	3a5468f251	Lock shards during querying and shutdown	8 years ago
