Fabian Reinartz	cb4dde7659	Fix WAL log recovery bug ... This fixes a bug where the last WAL file was closed after consuming it instead of being left open for further writes. Reloading of blocks on startup considers loading head blocks now.	8 years ago
Fabian Reinartz	3910b913bd	Revert interval overlap comparison changes	8 years ago
Fabian Reinartz	87805fb83f	Remove Partitioned* code	8 years ago
Fabian Reinartz	eedbebe1d7	Misc cleanups	8 years ago
Fabian Reinartz	50791a412e	Remove leaky Appender abstraction for hashedAppend	8 years ago
Fabian Reinartz	87d270fe11	Fix interval check, make DB shutdown concurrent	8 years ago
Fabian Reinartz	04783831e2	Correctly close compacted blocks.	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	3e569bc964	Optimize memory allocations in writer	8 years ago
Fabian Reinartz	ffb24a98f4	Add missing unlock, run debug endpoint in benchmark	8 years ago
Fabian Reinartz	92120448c2	Properly cleanup compacted dirs, fixes, docs	8 years ago
Fabian Reinartz	2c3e778d90	Compactor interface	8 years ago
Fabian Reinartz	2c3b56350a	Write meta.json file atomically	8 years ago
Fabian Reinartz	6c4217276f	Periodically trigger compaction ... This addresses an issue where the compaction triggered on cutting a new block doesn't find anything as the writers are still active on the block that should be ready for compaction.	8 years ago
Fabian Reinartz	db5c88ea9a	Misc compaction fixes	8 years ago
Fabian Reinartz	b281e4e39b	Accept prometheus.Registerer in constructor	8 years ago
Fabian Reinartz	306831f151	Add per-block state ULID	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	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	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	30d8866c13	Limit compaction range, make cut and compact concurrent	8 years ago
Fabian Reinartz	67d185ceb9	Compact based on compaction generation	8 years ago
Fabian Reinartz	d4779b374c	Properly track and write meta file	8 years ago
Fabian Reinartz	9ddbd64d00	Move stats into meta.json file, cleanup, docs	8 years ago
Fabian Reinartz	e006bc6dc6	Improve error messages, create regular dir for block	8 years ago
Fabian Reinartz	d2322f6095	Improve compaction processing	8 years ago
Fabian Reinartz	343dd9d94c	Fix wrong byte size in WAL base ref	8 years ago
Fabian Reinartz	dd0b69fe1b	Export ErrNotFound	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	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	c32a94d409	Unexport HeadBlock, export Block interface	8 years ago
Fabian Reinartz	29883a18fc	Add own Appender() method for DB	8 years ago
Fabian Reinartz	142c89b8b0	Fix/update metrics	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
