Current multi-window plan generation has problem on the project sequence, for example: +--LogicalWindow ( windowExpressions=[avg(sum_sales#115) WindowSpec(...) AS `avg_monthly_sales`#116, rank() WindowSpec(...) AS `rn`#117], ...) and correspond physical plan is: +--PhysicalWindow[6572]@16 ( windowFrameGroup=(Funcs=[avg(sum_sales#115) WindowSpec(...) AS `avg_monthly_sales`#116], ... ) +--PhysicalWindow[6568]@29 ( windowFrameGroup=(Funcs=[rank() WindowSpec(...) AS `rn`#117], ...] ) If the final plan is generated as following: MultiCastDataSinks STREAM DATA SINK EXCHANGE ID: 20 HASH_PARTITIONED: rn[#208], i_brand[#202], cc_name[#203], i_category[#201] Before we eventually resolve the multi-window issue, we add a projection as following and force a mapping but this will not cover all potential problems.
