@ravipesala @jackylk It looks like the discussion become uninteresting and
unproductive now. I just try to make some constructive comments. The comments
I made in the previous discussions remain true. In terms of MV, the
performance bottleneck comes from the amount of data we need to process and how
we process them, e.g. using cache, rather than matching time of the logical
plan. The reason I take the approach in chowbranch because the old code is
difficult to understand and to extend. This is not just my opinion. I will
stop here and not make any further comment.
