    • Columnstore - Technical debts in Optimizer / Rewriter

    Description

      There is a number of very banal query rewrite optimizations that we are not doing, paying an ugly performance price. Main examples are things like
      failure to flatten queries e.g. select count(c) from (select * from tbl). This epic is designed to hold all tickets related to it.
