[GitHub] [pinot] GSharayu opened a new issue #7462: Build execution plan without transform operator to optimize simple select queries

[GitBox <gi...@apache.org>]

GSharayu opened a new issue #7462:
URL: https://github.com/apache/pinot/issues/7462


   This issue is follow up of Issue(#6972): Implement PassThroughTransformOperator to optimize select queries. 
   
   If the user runs simple SELECT queries without involving any transformations, Pinot can help execute them faster by building a better query plan since Pinot has the information available during query compilation. Even though the query didn't have transforms, Pinot engine was still applying unnecessary NO-OP transformation. Improved query planning that skips the transformation phase from query execution plan leads to better performance for such queries. 
   
   This issue will build execution plan without transform operator, hence, for non transform queries, we will remove TransformOperator all together from query plan and execution. The root operator should be project operator
