Fabian Reinartz	54a7b98cff	Fix and test ref handling in DB appender	9 years ago
Brian Brazil	dba222b53c	Make rollback actually rollback. ... Also add tests for basic commit/rollback functionality. Fixes #39	9 years ago
Matt Bostock	4d5ca4b9c1	db: Fix typo: reference	9 years ago
Matt Bostock	3dd5a4ee09	db: Add comment: Appender not goroutine safe	9 years ago
Fabian Reinartz	778103b450	Add liecence file and headers	9 years ago
Fabian Reinartz	10c7c9acbe	Adjust import names to new repository organisation	9 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.	9 years ago
Fabian Reinartz	a52980e0a8	Add workaround for deadlocks ... This adds a workaround to avoid deadlocks for inconsistent write lock order across headBlocks. Things keep working if transactions only append data for the same timestamp, which is generally the case for Prometheus. Full behavior should be restored in a subsequent change.	9 years ago
Fabian Reinartz	e478d0e3bc	Actually close olds blocks in reloadBlocks ... This fixes a bug leaking memory because blocks were not actually closed as the closing call references the initial, empty slice	9 years ago
Fabian Reinartz	70909ca8ad	Ensure GC runs after each compactor call ... GC is triggered rarely, which may cause unnecessarily high memory spikes when running several compaction cycles in a row. Explicitly run GC so we don't have idle bytes marked as used from the previous cycle.	9 years ago
Fabian Reinartz	c18e055d7c	Fix races and add comments on remaining ones	9 years ago
Fabian Reinartz	9c93f8f2aa	Fix various races ... This fixes different race condition encoutnered when running Prometheus. It reduces the overall performance in the synthetic benchmark a fair bit but has no indiciations of impacting a real-world setup notably.	9 years ago
Fabian Reinartz	3635569257	Trigger reload correctly on interrupted compaction	9 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.	9 years ago
Fabian Reinartz	11be2cc585	Add composed Block interfaces, remove head generation ... This adds more lower-leve interfaces which are used to compose to different Block interfaces. The DB only uses interfaces instead of explicit persistedBlock and headBlock. The headBlock generation property is dropped as the use-case can be implemented using block sequence numbers.	9 years ago
Goutham Veeramachaneni	df7db4ac07	Update kit/log To New API ... NewContext has been removed couple of weeks back. Ref: https://github.com/go-kit/kit/releases/tag/v0.4.0	9 years ago
Fabian Reinartz	303a4ec3bc	Sync directory on retention delation	9 years ago
Fabian Reinartz	863d38dfee	Fix unreturned lock	9 years ago
Fabian Reinartz	d0770302ed	Add retention deletion	9 years ago
Fabian Reinartz	4962175218	Fix deadlock between heads and headmtx ... With hundreds of concurrent appenders the locking order between the headBlocks on instantiating appenders and write locking the headmtx is hard to impossible to get consistent. Just never instantiate appenders while holding the headmtx lock in any way.	9 years ago
Fabian Reinartz	65b846ae5b	Remove unreturned locks, detect writes on closed heads	9 years ago
Fabian Reinartz	32c32013a6	Fix loading of persisted blocks	9 years ago
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.	9 years ago
Fabian Reinartz	3910b913bd	Revert interval overlap comparison changes	9 years ago
Fabian Reinartz	87805fb83f	Remove Partitioned* code	9 years ago
Fabian Reinartz	eedbebe1d7	Misc cleanups	9 years ago
Fabian Reinartz	50791a412e	Remove leaky Appender abstraction for hashedAppend	9 years ago
Fabian Reinartz	87d270fe11	Fix interval check, make DB shutdown concurrent	9 years ago
Fabian Reinartz	04783831e2	Correctly close compacted blocks.	9 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.	9 years ago
Fabian Reinartz	3e569bc964	Optimize memory allocations in writer	9 years ago
Fabian Reinartz	ffb24a98f4	Add missing unlock, run debug endpoint in benchmark	9 years ago
Fabian Reinartz	92120448c2	Properly cleanup compacted dirs, fixes, docs	9 years ago
Fabian Reinartz	2c3e778d90	Compactor interface	9 years ago
Fabian Reinartz	2c3b56350a	Write meta.json file atomically	9 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.	9 years ago
Fabian Reinartz	db5c88ea9a	Misc compaction fixes	9 years ago
Fabian Reinartz	b281e4e39b	Accept prometheus.Registerer in constructor	9 years ago
Fabian Reinartz	306831f151	Add per-block state ULID	9 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.	9 years ago
Fabian Reinartz	a3b47c4929	Create default logger for DB	9 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.	9 years ago
Fabian Reinartz	79944a5912	Break out WAL into segment files	9 years ago
Fabian Reinartz	987a90d149	Don't delete files if retention duration is 0	9 years ago
