Björn Rabenstein	4ce01e9770	storage: Rename ...Values methods to At... (#9889) ... This mirrors #9888 for the richer iterators we have with histograms in the game. Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago
Björn Rabenstein	d677aa4b29	storage: Consolidate iterator method names (Values -> At) (#9888) ... `BufferedSeriesIterator` and `MemoizedSeriesIterator` use a method called `Values` for exactly the purpose for which all other iterators of the same kind use a method called `At`. That alone is confusing, but on top of that, the `Values` method only returns a single sample, not multiple values. I assume the naming has historical reasons. This commit makes it more consistent. It is now easier to read, and now `BufferedSeriesIterator` and `MemoizedSeriesIterator` implement `chunkenc.Iterator` like many other iterators, too.

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
