Fabian Reinartz	5a1c8eaa0e	Fix missing appends after reference lookups	8 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.	8 years ago

Fabian Reinartz	fde69dab49	Use buffer pool for head appenders	8 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.	8 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.	8 years ago

Fabian Reinartz	d86e8a63c7	Report correct number of appended samples	8 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	8 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.	8 years ago

Fabian Reinartz	ee217adc7e	Redfine append interface, remove old Prometheus storage from bench	8 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.	8 years ago
