Subject Re: Re: Histograms and statistics on Asterix

Hi, Wail
   We are doing some work about how to construct the histogram (both equal-width and equal-height)
on the fly, and will further apply it onto
our parallel sort code base.
   Just ping us if you need more information.
   Hope to talk/study more advanced features of histogram with you.
Best,
Wenhai
