Goutham Veeramachaneni	203012169a	snapshot: Remove truncation check to restore func. Signed-off-by: Goutham Veeramachaneni <cs14btech11014@iith.ac.in>	7 years ago
Fabian Reinartz	162a48e4f2	Create series with ID recorded in WAL when reading it back	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	1ddedf2b30	Change series ID from uint32 to uint64	7 years ago
Fabian Reinartz	af2c2f9674	Re-enable head block delet test	7 years ago
Fabian Reinartz	893b6ec506	Add tests for GC and chunk truncation	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

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	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	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
Fabian Reinartz	ca1bc920b7	Test updates	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	f1435f2e2c	Track appended samples properly in metric	8 years ago
Fabian Reinartz	9790aa98ac	Add postings wrapper that emits head postings in label set order This adds a position mapper that takes series from a head block in the order they were appended and creates a mapping representing them in order of their label sets. Write-repair of the postings list would cause very expensive writing. Hence, we keep them as they are and only apply the postition mapping at the very end, after a postings list has been sufficienctly reduced through intersections etc.	8 years ago
