Filip Petkovski	6e68046c25	Implement histogram statistics decoder (#14097 ) Implement histogram statistics decoder This commit speeds up histogram_count and histogram_sum functions on native histograms. The idea is to have separate decoders which can be used by the engine to only read count/sum values from histogram objects. This should help with reducing allocations when decoding histograms, as well as with speeding up aggregations like sum since they will be done on floats and not on histogram objects.

Bryan Boreham	ea82b49c33	[ENHANCEMENT] PromQL: use Kahan summation for sum() This can give a more precise result, by keeping a separate running compensation value to accumulate small errors.

Arve Knudsen	a25160e6a4	[REFACTOR] PromQL: simplify rangeEvalTimestampFunctionOverVectorSelector (#14021 ) The function `rangeEvalTimestampFunctionOverVectorSelector` appeared to be checking histogram size, however the value it used was always 0 due to subtle variable shadowing. However we don't need to pass sample values to the `timestamp` function, since the latter only cares about timestamps. This also affects peak sample count in statistics, since we are no longer copying histogram samples. Signed-off-by: Arve Knudsen <arve.knudsen@gmail.com>	7 months ago

Bryan Boreham	2cf3c9de8f	promql: store labels per-group only for count_values This saves memory in other kinds of aggregation. We don't need `orderedResult` in `aggregationCountValues`; the ordering is not guaranteed. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	8 months ago

Bryan Boreham	2f03acbafc	promql: refactor: split topk/bottomk from sum/avg/etc They aggregate results in different ways. topk/bottomk don't consider histograms so can simplify data collection. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	8 months ago
Bryan Boreham	74eed67ef6	promql: refactor: pull fetching input data out of rangeEvalAgg This is a cleaner split of responsibilities. We now check the sample count after calling rangeEvalAgg.

Bryan Boreham	cb6c4b3092	promql: simplify k/q parameter to topk/bottomk/quantile Pass it as a float64 not as interface{}. Make k a simple int, since that is the parameter to make(). Pull invalid quantile warning out of the loop. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	8 months ago

Bryan Boreham	5f10d17cef	promql: refactor: split out aggregations over range The new function `rangeEvalAgg` is mostly a copy of `rangeEval`, but without `initSeries` which we don't need and inlining the callback to `aggregation()`. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	8 months ago

Bryan Boreham	29244fb841	promql: refactor: extract count_values implementation The existing aggregation function is very long and covers very different cases. `aggregationCountValues` is just for `count_values`, which differs from other aggregations in that it outputs as many series per group as there are values in the input. Remove the top-level switch on string parameter type; use the same `Op` check there as elswehere. Pull checking parameters out to caller, where it is only executed once.
