beorn7	817a2396cb	Name float values as "floats", not as "values" In the past, every sample value was a float, so it was fine to call a variable holding such a float "value" or "sample". With native histograms, a sample might have a histogram value. And a histogram value is still a value. Calling a float value just "value" or "sample" or "V" is therefore misleading. Over the last few commits, I already renamed many variables, but this cleans up a few more places where the changes are more invasive. Note that we do not to attempt naming in the JSON APIs or in the protobufs. That would be quite a disruption. However, internally, we can call variables as we want, and we should go with the option of avoiding misunderstandings. Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago
beorn7	630bcb494b	storage: Use separate sample types for histogram vs. float Previously, we had one “polymorphous” `sample` type in the `storage` package. This commit breaks it up into `fSample`, `hSample`, and `fhSample`, each still implementing the `tsdbutil.Sample` interface. This reduces allocations in `sampleRing.Add` but inflicts the penalty of the interface wrapper, which makes things worse in total. This commit therefore just demonstrates the step taken. The next commit will tackle the interface overhead problem. Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago

Björn Rabenstein	7e42acd3b1	tsdb: Rework iterators (#9877 ) - Pick At... method via return value of Next/Seek. - Do not clobber returned buckets. - Add partial FloatHistogram suppert. Note that the promql package is now _only_ dealing with FloatHistograms, following the idea that PromQL only knows float values. As a byproduct, I have removed the histogramSeries metric. In my understanding, series can have both float and histogram samples, so that metric doesn't make sense anymore. As another byproduct, I have converged the sampleBuf and the histogramSampleBuf in memSeries into one. The sample type stored in the sampleBuf has been extended to also contain histograms even before this commit. Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago

Bartlomiej Plotka	e6d7cc5fa4	tsdb: Added ChunkQueryable implementations to db; unified MergeSeriesSets and vertical to single struct. (#7069 ) * tsdb: Added ChunkQueryable implementations to db; unified compactor, querier and fanout block iterating. Chained to https://github.com/prometheus/prometheus/pull/7059 * NewMerge(Chunk)Querier now takies multiple primaries allowing tsdb DB code to use it. * Added single SeriesEntry / ChunkEntry for all series implementations. * Unified all vertical, and non vertical for compact and querying to single merge series / chunk sets by reusing VerticalSeriesMergeFunc for overlapping algorithm (same logic as before) * Added block (Base/Chunk/)Querier for block querying. We then use populateAndTomb(Base/Chunk/) to iterate over chunks or samples. * Refactored endpoint tests and querier tests to include subtests.
