zenador	81862aabd7	[nhcb branch] Add basic unit tests for native histograms with custom buckets converted from classic histograms (#13794 ) * modify unit test framework to automatically generate native histograms with custom buckets from classic histogram series * add very basic tests for classic histogram converted into native histogram with custom bounds * fix histogram_quantile for native histograms with custom buckets * make loading with nhcb explicit * evaluate native histograms with custom buckets on queries with explicit keyword * use regex replacer * use temp histogram struct for automatically loading converted nhcb Signed-off-by: Jeanette Tan <jeanette.tan@grafana.com> Signed-off-by: George Krajcsovits <krajorama@users.noreply.github.com>	7 months ago
zenador	4acbb7dea6	Add custom buckets to native histogram chunks encoding (#13706 ) * add custom bounds to chunks encoding * change custom buckets schema number * rename custom bounds to custom values Signed-off-by: Jeanette Tan <jeanette.tan@grafana.com>	8 months ago
György Krajcsovits	5d0a0a7542	Add custom buckets to native histogram model (#13592 ) * add custom buckets to native histogram model * simple copy for custom bounds * return errors for unsupported add/sub operations * add test cases for string and update appendhistogram in scrape to account for new schema * check fields which are supposed to be unused but may affect results in equals * allow appending custom buckets histograms regardless of max schema Signed-off-by: Jeanette Tan <jeanette.tan@grafana.com>	9 months ago

Linas Medziunas	49613823f8	Reuse slices in [Float]Histogram.ReduceResolution Signed-off-by: Linas Medziunas <linas.medziunas@gmail.com>	1 year ago
Ziqi Zhao	ab2a7bb74f	add generic shrink function (#13001 ) Add `ReduceResolution` method to `Histogram` and `FloatHistogram` This takes the original `mergeToSchema` function and turns it into a more generic `reduceResolution` function, which is the building block for the new methods. The methods will help with addressing #12864. --------- Signed-off-by: Ziqi Zhao <zhaoziqi9146@gmail.com>	1 year ago

beorn7	9aadd54786	histogram: Fix bounds of buckets returned by floatBucketIterator The bounds weren't really used so far, so no actual bug in the code so far. But it's obviously confusing if the bounds returned by a floatBucketIterator with a target schema different from the original schema are wrong. Signed-off-by: beorn7 <beorn@grafana.com>	1 year ago
Marc Tudurí	9474610baf	Support FloatHistogram in TSDB (#11522 ) Extends Appender.AppendHistogram function to accept the FloatHistogram. TSDB supports appending, querying, WAL replay, for this new type of histogram.

beorn7	bf0847073d	histogram: Modify getBound to deal properly with infinity The bucket receiving math.MaxFloat64 observations now has math.MaxFloat64 as upper bound, while the bucket after it (the last possible bucket) has +Inf. This also adds a test for getBound and moves the getBound code to generic.go (where it should have been in the first place). Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago
Björn Rabenstein	dccfb9db4e	histogram: Remove code replication via generics (#11361 ) * histogram: Simplify iterators We don't really need currLower and currUpper and can calculate it when needed (as already done for the floatBucketIterator). The calculation is cheap, while keeping those extra variables around costs RAM (potentially a lot with many iterators). * histogram: Convert Bucket/FloatBucket to one generic type * histogram: Move some bucket iterator code into generic base iterator * histogram: Remove cumulative iterator for FloatHistogram We added it in the past for completeness (Histogram has one), but it has never been used. Plus, even the cumulative iterator for Histogram is only there for test reasons. We can always add it back, and then maybe even using generics. Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago
