Ilya Matiach commented on SPARK-19208   Re: MultivariateOnlineSummarizer performance optimization zhengruifeng your api looks great to me. I agree with you that we need to make sure when computing multiple statistics that use the same temporary variables we should only compute them once. Joseph K. Bradley is there a way to combine your api with the proposed one so that temporary common variables will only be computed once?
