Goutham Veeramachaneni	5579efbd5b	Initial implentation of Deletes on persistedBlock ... Very much a WIP Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in>	8 years ago

Fabian Reinartz	535532ca02	Export refdSample ... The type was part of a exported method signatures and should therefore be exported as well.	8 years ago

Goutham Veeramachaneni	2fa647f50b	Fix missing postings in Merge and Intersect (#77) ... * Test for a previous implematation of Intersect Before we were moving the postings list everytime we create a new chained `intersectPostings`. That was causing some postings to be skipped. This test fails on the older version. Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in> * Advance on Seek only when valid. Issue: Before in mergedPostings and others we advance everytime we `Seek`, which causes issues with `Intersect`. Take the case, where we have a mergedPostings = m merging, a: {10, 20, 30} and b: {15, 25, 35}. Everytime we `Seek`, we do a.Seek and b.Seek. Now if we Intersect m with {21, 22, 23, 30}, we would do Seek({21,22,23}) which would advance a and b beyond 30. Fix: Now we advance only when the seeking value is greater than the current value, as the definition specifies. Also, posting 0 will not be a valid posting and will be used to signal finished or un-initialized PostingsList. Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in> * Add test for Merge+Intersect edgecase. Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in> * Add comments to trivial tests. Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in>	8 years ago

Goutham Veeramachaneni	adaf4d2099	Handle duplicate & out of order values in same txn ... Add docs about not erroring out on exact dupes. Moved tests to require.* Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in>	8 years ago
Brian Brazil	72443bddfc	Remove dead code.	8 years ago
Brian Brazil	bceb5c1b16	When checking for amended points, do it in terms of bits. ... NaN != NaN, so the previous code would incorrectly report it as changed. There's also plans to take advantage of the NaN payload, so look at the entire value.	8 years ago
Fabian Reinartz	778103b450	Add liecence file and headers	8 years ago
Fabian Reinartz	c73a397da2	Adjust maximum samples per chunk.	8 years ago
Goutham Veeramachaneni	a51b2666d7	Fix Panic When Accessing Uncut memorySeries ... When calling AddFast, we check the details of the head chunk of the referred memorySeries. But it could happen that there are no chunks in the series at all. Currently, we are deferring chunk creation to when we actually append samples, but we can be sure that there will be samples if the series is created. We will be consuming no extra memory by cutting a chunk when we create the series. Ref: #28 comment 2 Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in>	8 years ago

Fabian Reinartz	87d48bf9de	Merge branch 'master' of github.com:fabxc/tsdb	8 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.	8 years ago
Goutham Veeramachaneni	61f866bb94	Add Sample Back ... The compilation and tests are broken as head.go requires sample which has been moved to another package while moving BufferedSeriesIterator. Duplication seemed better compared to exposing sample from tsdbutil.	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	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	8 years ago

Fabian Reinartz	e837034360	Merge pull request #14 from Gouthamve/log-update ... Update kit/log To New API	8 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.	8 years ago
Fabian Reinartz	3635569257	Trigger reload correctly on interrupted compaction	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
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.	8 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	8 years ago
Fabian Reinartz	65b846ae5b	Remove unreturned locks, detect writes on closed heads	8 years ago
Fabian Reinartz	e0b33a7a28	Remove leftover signaling channels from headBlock	8 years ago
Fabian Reinartz	34efe4e2c8	Drop position mapper from head block ... The position mapper was intended to pre-computed "expensive" ordering of label sets. It was expensive to update and caused a lot of trouble. Skipping this optimization entirely actually revelead it was pointless and even harmful from the e2e perspective.	8 years ago
Fabian Reinartz	ad5812d83a	Handle WAL corruption by truncating ... This adds handling for various corruption scenarios of the WAL. If corruption is encountered, we truncate the WAL after the last valid entry transparently and continue appending after the offset.	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	e825a0b40c	Make mapper updates asynchronous	8 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.	8 years ago
Fabian Reinartz	87805fb83f	Remove Partitioned* code	8 years ago
Fabian Reinartz	50791a412e	Remove leaky Appender abstraction for hashedAppend	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	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
