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
