Thanks @cj-zhukov ! I think it would be super helpful to make an example / test showing how to use this new distribution to estimate cardinality For example perhaps you could set up a SampledDistribition like ``` [0, 10]: 100 samples [20,30]: 200 samples ``` And then estimate the cardinality of a predicate like `x > 25` I would expect the estimate to be 1/3 (half of the 20-30 bucket and none of the 1-10 bucket) -- This is an automated message from the Apache Git Service.
