Fiona Liao	5bee0cfce2	Change `ChunkReader.Chunk()` to `ChunkOrIterable()` The ChunkReader interface's Chunk() has been changed to ChunkOrIterable(). This is a precursor to OOO native histogram support - with OOO native histograms, the chunks.Meta passed to Chunk() can result in multiple chunks being returned rather than just a single chunk (e.g. if oooMergedChunk has a counter reset in the middle). To support this, ChunkOrIterable() requires either a single chunk or an iterable to be returned. If an iterable is returned, the caller has the responsibility of converting the samples from the iterable into possibly multiple chunks. The OOOHeadChunkReader now returns an iterable rather than a chunk to prepare for the native histograms case. Also as a beneficial side effect, oooMergedChunk and boundedChunk has been simplified as they only need to implement the Iterable interface now, not the full Chunk interface. --------- Signed-off-by: Fiona Liao <fiona.y.liao@gmail.com> Co-authored-by: George Krajcsovits <krajorama@users.noreply.github.com>	1 year ago
Arve Knudsen	ecc37588b0	tsdb: seriesHashmap.set by making receiver a pointer (#13193 ) * Fix tsdb.seriesHashmap.set by making receiver a pointer The method tsdb.seriesHashmap.set currently doesn't set the conflicts field properly, due to the receiver being a non-pointer. Fix by turning the receiver into a pointer, and add a corresponding regression test. Signed-off-by: Arve Knudsen <arve.knudsen@gmail.com>	1 year ago

zenador	ccfe14d7e7	PromQL: ignore small errors for bucketQuantile (#13153 ) promql: Improve histogram_quantile calculation for classic buckets Tiny differences between classic buckets are most likely caused by floating point precision issues. With this commit, relative changes below a certain threshold are ignored. This makes the result of histogram_quantile more meaningful, and also avoids triggering the _input to histogram_quantile needed to be fixed for monotonicity_ annotations in unactionable cases. This commit also adds explanation of the new adjustment and of the monotonicity annotation to the documentation of `histogram_quantile`. --------- Signed-off-by: Jeanette Tan <jeanette.tan@grafana.com>	1 year ago

Łukasz Mierzwa	870627fbed	Add enable_compression scrape config option Currently Prometheus will always request gzip compression from the target when sending scrape requests. HTTP compression does reduce the amount of bytes sent over the wire and so is often desirable. The downside of compression is that it requires extra resources - cpu & memory. This also affects the resource usage on the target since it has to compress the response before sending it to Prometheus. This change adds a new option to the scrape job configuration block: enable_compression. The default is true so it remains the same as current Prometheus behaviour. Setting this option to false allows users to disable compression between Prometheus and the scraped target, which will require more bandwidth but it lowers the resource usage of both Prometheus and the target.

Oleg Zaytsev	f997c72f29	Make head block ULIDs descriptive (#13100 ) * Make head block ULIDs descriptive As far as I understand, these ULIDs aren't persisted anywhere, so it should be safe to change them.

zenador	32ee1b15de	Fix error on ingesting out-of-order exemplars (#13021 ) Fix and improve ingesting exemplars for native histograms. See code comment for a detailed explanation of the algorithm. Note that this changes the current behavior for all kind of samples slightly: We now allow exemplars with the same timestamp as during the last scrape if the value or the labels have changed. Also note that we now do not ingest exemplars without timestamps for native histograms anymore.
