[pick](nereids) using mv's derived stats (#35721)

Open englefly opened this issue 1 year ago • 2 comments

for a given mv, we have 2 stats. one is generated by stats analyzer, which is accurate, another is derived stats, which is derived when optimizer runs the mv query. If a query tree contains a mv, we will use the mv's derived stats to derive stats for the whole tree.
