Fabian Reinartz	e5ce2bef43	Add explicit error to Querier.Select ... This has been a frequent source of debugging pain since errors are potentially delayed to a much later point. They bubble up in an unrelated execution path.	7 years ago
Julius Volz	1dad3370fd	Close WAL when closing the DB ... Also, the `wal` field of the `DB` was not used anywhere, so this removes it.	7 years ago
Fabian Reinartz	82796db37b	Ensure near-empty chunks end at correct boundary ... We were determining a chunk's end time once it was one quarter full to compute it so all chunks have uniform number of samples. This accidentally skipped the case where series started near the end of a chunk range/block and never reached that threshold. As a result they got persisted but were continued across the range. This resulted in corrupted persisted data.	7 years ago
Fabian Reinartz	c3e502b194	Merge pull request #168 from prometheus/fasterwal ... wal: decode and process in separate threads.	7 years ago
Fabian Reinartz	fb9da52b11	Add more verbose error handling for closing, reduce locking ... This commit introduces error returns in various places and is explicit about closing persisted blocks. {Index,Chunk,Tombstone}Readers are more consistent about their Close() method. Whenever a reader is retrieved, the corresponding close method must eventually be called. We use this to track pending readers against persisted blocks. Querier's against the DB no longer hold a read lock for their entire lifecycle. This avoids long running queriers to starve new ones when we have to acquire a write lock when reloading blocks.	7 years ago

Fabian Reinartz	7ada9cd805	Simplify series create logic in head	7 years ago
Fabian Reinartz	c36d574290	Replace single head lock with granular locks ... This adds various new locks to replace the single big lock on the head. All parts now must be COW as they may be held by clients after initial retrieval. Series by ID and hashes are now held in a stripe lock to reduce contention and total holding time during GC. This should reduce starvation of readers.	7 years ago

Fabian Reinartz	5cf2662074	Refactor WAL into Head and misc improvements	7 years ago
Fabian Reinartz	3901b6e70b	Remove multiple heads ... This changes the structure to a single WAL backed by a single head block. Parts of the head block can be compacted. This relieves us from any head amangement and greatly simplifies any consistency and isolation concerns by just having a single head.	7 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	10c7c9acbe	Adjust import names to new repository organisation	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
