As for t-digest vs. KLL or ReqSketch comparison, we have [a paper](https://arxiv.org/abs/2102.09299) with Graham and people from Splunk. I think t-digest was not updated much since then, so I think you can point to this paper for comparison. The upshot is that while t-digest is more accurate on well-behaved distributions, there are examples and distributions where it fails spectacularly (though these inputs are somewhat artificial). However, KLL and ReqSketch have much better update time than t-digest. -- This is an automated message from the Apache Git Service.
