Callum Styan	bcde61b237	we shouldn't assume we'll receive the labels in sorted order	9 years ago
Callum Styan	8326e410d0	decouple tsdb main.go (and tests) from prometheus/pkg	9 years ago
Fabian Reinartz	d226411a2a	db: delete old blocks during reload ... Windows requires blocks to be closed before deleting their directories. This adds a set of deleteable blocks to reload(), which then deletes them without causing disruption to querying.	9 years ago

Fabian Reinartz	6892fc6dcb	Finish old WAL segment async, default to no fsync ... We were still fsyncing while holding the write lock when we cut a new segment. Given we cannot do anything but logging errors, we might just as well complete segments asynchronously. There's not realistic use case where one would fsync after every WAL entry, thus make the default of a flush interval of 0 to never fsync which is a much more likely use case.	9 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.	9 years ago
Fabian Reinartz	3951d8cc29	Fix selection of compactable blocks	9 years ago
Fabian Reinartz	9c4235532e	Fix compaction selection after creating new heads ... This fixes the case where between block creations no compaction plans are ran. We were not compacting anything in these cases since the on creation the most recent head block always had a high timestamp of 0.	9 years ago

Fabian Reinartz	5a1c8eaa0e	Fix missing appends after reference lookups	9 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.	9 years ago
Fabian Reinartz	c20cc44b06	Add docs, write sequence number to meta.json	9 years ago
Fabian Reinartz	5fb01d41aa	Use new Prometheus text format parser	10 years ago
Fabian Reinartz	fde69dab49	Use buffer pool for head appenders	10 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.	10 years ago
Fabian Reinartz	80affd98a8	Add barrier to benchmark writer ... This adds a barrier to avoid issues with unfair goroutine scheduling that causes some fake scrapers to run away from the other ones.	10 years ago

Fabian Reinartz	d86e8a63c7	Report correct number of appended samples	10 years ago
Fabian Reinartz	300f4e2abf	Use separate lock for series creation ... This uses the head block's own lock to only lock if new series were encountered. In the general append case we just need to hold a	10 years ago
Fabian Reinartz	c61b310210	Naive size-based compaction ... This adds naive compaction that tries to compact three blocks of roughly equal size. It decides based on samples present in a block and has no safety measures considering the actual file size.	10 years ago
Fabian Reinartz	3ed2c2a14b	Rename Partition to regular DB, DB to PartitionedDB	10 years ago
Fabian Reinartz	cabd7e4ebc	Add small testdata file	10 years ago

Fabian Reinartz	ee217adc7e	Redfine append interface, remove old Prometheus storage from bench	10 years ago
Fabian Reinartz	e561c91d53	Implement proper buffered iterator ... This adds a proper duration based lookback buffer for series iterators to allow advancing sequentially while remaining able to calculate time aggregating functions such as `rate` backwards. It uses an array ring buffer to minimize heap allocations for potentially hundreds of thousands of series for a single query.	10 years ago
