Fabian Reinartz	89d8467f5c	Add missing lock	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	54f5027406	Put WAL lock down into encoder	8 years ago
Fabian Reinartz	300f4e2abf	Use separate lock for series creation ... This uses the head block's own lock to only lock if new series were encountered. In the general append case we just need to hold a	8 years ago
Fabian Reinartz	63e12807da	Don't update head postings mapper on every append	8 years ago
Fabian Reinartz	71efd2e08d	Periodically fsync WAL, make head cut async	8 years ago
Fabian Reinartz	c61b310210	Naive size-based compaction ... This adds naive compaction that tries to compact three blocks of roughly equal size. It decides based on samples present in a block and has no safety measures considering the actual file size.	8 years ago
Fabian Reinartz	2eb544c98e	Change file names and maker parsing safer	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	937cdb579c	Switch to sequential block names ... This changes block directory names from the int64 timestamp to sequential numbering.	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	5aa7f7cce8	Compact head block into persisted block	8 years ago
Fabian Reinartz	3f72d5d027	Fix last timestamp initialization ... This initializes the chunkDesc's last timestamp to the minimum value so initial samples with a timestamp of 0 (e.g. in tests) are not accidentally dropped.	8 years ago
Fabian Reinartz	40cf215fba	Hotfix missing sorting of head block series index	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	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.	8 years ago
Fabian Reinartz	5d7ec06e04	Use ChunkMeta in SeriesWriter	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	1e1a37b15b	Remove double-reference in chunk hashmap	8 years ago
Fabian Reinartz	675f0886f0	Append to chunks cannot error	8 years ago
