Björn Rabenstein	0e1b9dd308	Promql: Initial rate implementation for sparse histograms (#9926) ... Signed-off-by: beorn7 <beorn@grafana.com>	3 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
beorn7	6a820a646c	histogram: Add FloatHistogram ... Including a few adjustments for normal Histogram, too, e.g. use pointer receiver to avoid the large copy on method calls. Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago
