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	10a82f87fd	Enable reusing memory when converting between histogram types The 'ToFloat' method on integer histograms currently allocates new memory each time it is called. This commit adds an optional *FloatHistogram parameter that can be used to reuse span and bucket slices. It is up to the caller to make sure the input float histogram is not used anymore after the call. Signed-off-by: Filip Petkovski <filip.petkovsky@gmail.com>	12 months ago
