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	a3b47c4929	Create default logger for DB	8 years ago
Fabian Reinartz	f734773214	Replace per-file locking with single PID lock file ... File locks have a multitude of problems that make them hard to use correctly. As they are just advisory, they are only meaningful to prevent accidents like running the same process twice. A simple PID file lock works reliably in those cases and is simpler.	8 years ago
Fabian Reinartz	c808928b90	SeriesWriter -> ChunkWriter ... This commit simplifies a SeriesWriter into a ChunkWriter and detaches it entirely from the notion of a series and the series index.	8 years ago
Fabian Reinartz	a3d042b54e	Support multiple chunk files in read path	8 years ago
Fabian Reinartz	afa084920c	Use Castagnoli polynomial for CRC32s; cache them	8 years ago
Fabian Reinartz	9c7a88223e	Add full encode/decode WAL cycle test	8 years ago
Fabian Reinartz	2c97428a79	Add basic WAL tests	8 years ago
Fabian Reinartz	84e8027a8e	Close consumed WAL segments, verify checksums on read	8 years ago
Fabian Reinartz	eeb03e97e2	Add headers and format flag for WAL segments	8 years ago
Fabian Reinartz	79944a5912	Break out WAL into segment files	8 years ago
Fabian Reinartz	987a90d149	Don't delete files if retention duration is 0	8 years ago
Fabian Reinartz	9c76624df2	Add initial retention cutoff	8 years ago
Fabian Reinartz	f1435f2e2c	Track appended samples properly in metric	8 years ago
Fabian Reinartz	012cf4ef25	Count writer references on head blocks	8 years ago
Fabian Reinartz	5a1c8eaa0e	Fix missing appends after reference lookups	8 years ago
Fabian Reinartz	f556036037	Close blocks before overwriting with compacted one ... This prevents the meta.json file of a compacted block to be overwritten with data of the old block.	8 years ago
Fabian Reinartz	ac5229e1b4	Correctly write empty blocks and extend appenders by new blocks	8 years ago
Fabian Reinartz	42fa342229	Improve multi-head handling ... This improves handling of multiple head blocks. Configuration is simplified to specify the number of concurrently appendable blocks.	8 years ago
Fabian Reinartz	30efe4a58c	Support writing to multiple head blocks ... This is an initial (and hacky) first pass on allowing appending to multiple blocks simultaniously to avoid dropping samples right after cutting a new head block. It's also required for cases like the PGW, where a scrape may contain varying timestamps.	8 years ago
Fabian Reinartz	a61a31a5d7	compaction: add fast-path for compacting mem blocks	8 years ago
Fabian Reinartz	c20cc44b06	Add docs, write sequence number to meta.json	8 years ago

Fabian Reinartz	5fb01d41aa	Use new Prometheus text format parser	8 years ago
Fabian Reinartz	dd0b69fe1b	Export ErrNotFound	8 years ago
Fabian Reinartz	9cf49f68e9	wal: use larger buffer	8 years ago
Fabian Reinartz	1c80c33e72	Fix bug of unsorted postings lists being created ... The former approach created unordered postings list by either map iteration of new series being unsorted (fixable) or concurrent writers creating new series interleaved. We switch back to generating ephemeral references for a single batch. Newly created series have to be re-set upon the next insert.	8 years ago
Fabian Reinartz	c7f5590a71	Ensure order of postings when adding new series	8 years ago
Fabian Reinartz	d970f0256a	Add Rollback() and docs to Appender interface	8 years ago
Fabian Reinartz	22db9c3413	Remove old appendBatch methods	8 years ago
Fabian Reinartz	fde69dab49	Use buffer pool for head appenders	8 years ago
Fabian Reinartz	a317f252b9	Expose series references to clients ... This exposes a reference number of a series represented by a label set to clients. Subsequent samples can be directly added via the reference rather than repeatedly passing in the full labels. This drasitcally speeds up the append process. The appender chain uses different sections of the reference number for assignment to child appenders and invalidating reference numbers as necessary. Clients can either pass out reference numbers themselves or have their own optimized lookup, i.e. by directly associating unparsed metric descriptors strings with reference numbers.	8 years ago
Fabian Reinartz	5e028710d5	Add fast past to validation after lock switch	8 years ago
Fabian Reinartz	1b39887baa	Revalidate series existance after lock switch	8 years ago
Fabian Reinartz	ca5791efbc	Simplify creation of new series	8 years ago
Fabian Reinartz	0ca755b4ae	Replace single head chunk per series with memSeries ... This adds a memory series holding several chunk to replace the single head chunk per series so far. This is necessary for uniform maximum chunk sizes in cases where some series have higher frequency samples than others.	8 years ago
Fabian Reinartz	80affd98a8	Add barrier to benchmark writer ... This adds a barrier to avoid issues with unfair goroutine scheduling that causes some fake scrapers to run away from the other ones.	8 years ago
Fabian Reinartz	c32a94d409	Unexport HeadBlock, export Block interface	8 years ago
Fabian Reinartz	d86e8a63c7	Report correct number of appended samples	8 years ago
