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.

beorn7	7f912db15a	promql: Fix limiting of extrapolation to negative values This is a bit tough to explain, but I'll try: `rate` & friends have a sophisticated extrapolation algorithm. Usually, we extrapolate the result to the total interval specified in the range selector. However, if the first sample within the range is too far away from the beginning of the interval, or if the last sample within the range is too far away from the end of the interval, we assume the series has just started half a sampling interval before the first sample or after the last sample, respectively, and shorten the extrapolation interval correspondingly. We calculate the sampling interval by looking at the average time between samples within the range, and we define "too far away" as "more than 110% of that sampling interval". However, if this algorithm leads to an extrapolated starting value that is negative, we limit the start of the extrapolation interval to the point where the extrapolated starting value is zero. At least that was the intention. What we actually implemented is the following: If extrapolating all the way to the beginning of the total interval would lead to an extrapolated negative value, we would only extrapolate to the zero point as above, even if the algorithm above would have selected a starting point that is just half a sampling interval before the first sample and that starting point would not have an extrapolated negative value. In other word: What was meant as a _limitation_ of the extrapolation interval yielded a _longer_ extrapolation interval in this case. There is an exception to the case just described: If the increase of the extrapolation interval is more than 110% of the sampling interval, we suddenly drop back to only extrapolate to half a sampling interval. This behavior can be nicely seen in the testcounter_zero_cutoff test, where the rate goes up all the way to 0.7 and then jumps back to 0.6. This commit changes the behavior to what was (presumably) intended from the beginning: The extension of the extrapolation interval is only limited if actually needed to prevent extrapolation to negative values, but the "limitation" never leads to _more_ extrapolation anymore. The difference is subtle, and probably it never bothered anyone. However, if you calculate a rate of a classic histograms, the old behavior might create non-monotonic histograms as a result (because of the jumps you can see nicely in the old version of the testcounter_zero_cutoff test). With this fix, that doesn't happen anymore. Signed-off-by: beorn7 <beorn@grafana.com>	9 months ago

beorn7	86d7618d84	promql: Fix wrongly scoped range vectors Fixes #11708. If a range vector is fixen in time with the @ modifier, it gets still moved around for different steps in a range query. Since no additional points are retrieved from the TSDB, this leads to steadily emptying the range, leading to the weird behavior described in isse #11708. This only happens for functions listed in `AtModifierUnsafeFunctions`, and the only of those that takes a range vector is `predict_linear`, which is the reason why we see it only for this particular function.

Filip Petkovski	583f3e587c	Optimize histogram iterators (#13340 ) Optimize histogram iterators Histogram iterators allocate new objects in the AtHistogram and AtFloatHistogram methods, which makes calculating rates over long ranges expensive. In #13215 we allowed an existing object to be reused when converting an integer histogram to a float histogram. This commit follows the same idea and allows injecting an existing object in the AtHistogram and AtFloatHistogram methods. When the injected value is nil, iterators allocate new histograms, otherwise they populate and return the injected object. The commit also adds a CopyTo method to Histogram and FloatHistogram which is used in the BufferedIterator to overwrite items in the ring instead of making new copies. Note that a specialized HPoint pool is needed for all of this to work (`matrixSelectorHPool`). --------- Signed-off-by: Filip Petkovski <filip.petkovsky@gmail.com> Co-authored-by: George Krajcsovits <krajorama@users.noreply.github.com>	10 months ago

Filip Petkovski	1f69dcfa6b	Fix reusing float histograms In https://github.com/prometheus/prometheus/pull/13276 we started reusing float histogram objects to reduce allocations in PromQL. That PR introduces a bug where histogram pointers gets copied to the beginning of the histograms slice, but are still kept in the end of the slice. When a new histogram is read into the last element, it can overwrite a previous element because the pointer is the same. This commit fixes the issue by moving outdated points to the end of the slice so that we don't end up with duplicate pointers in the same buffer. In other words, the slice gets rotated so that old objects can get reused. Signed-off-by: Filip Petkovski <filip.petkovsky@gmail.com>	12 months ago
