Description
Here is an example query with the corresponding logical plan. The project contains unnecessary columns L_ORDERKEY, O_ORDERKEY in the projection even when it is not required by subsequent operators e.g. DrillJoinRel.
EXPLAIN PLAN without implementation FOR SELECT L.L_QUANTITY FROM cp.`tpch/lineitem.parquet` L, cp.`tpch/orders.parquet` O WHERE cast(L.L_ORDERKEY as int) = cast(O.O_ORDERKEY as int);

DrillProjectRel(L_QUANTITY=[$1])
DrillJoinRel(condition=[=($2, $4)], joinType=[inner])
DrillProjectRel(L_ORDERKEY=[$0], L_QUANTITY=[$1], $f2=[CAST($0):INTEGER])
DrillScanRel(table=[[cp, tpch/lineitem.parquet]], groupscan=[ParquetGroupScan [entries=[ReadEntryWithPath [path=classpath:/tpch/lineitem.parquet]], selectionRoot=classpath:/tpch/lineitem.parquet, numFiles=1, numRowGroups=1, usedMetadataFile=false, columns=[`L_ORDERKEY`, `L_QUANTITY`]]])
DrillProjectRel(O_ORDERKEY=[$0], $f1=[CAST($0):INTEGER])
DrillScanRel(table=[[cp, tpch/orders.parquet]], groupscan=[ParquetGroupScan [entries=[ReadEntryWithPath [path=classpath:/tpch/orders.parquet]], selectionRoot=classpath:/tpch/orders.parquet, numFiles=1, numRowGroups=1, usedMetadataFile=false, columns=[`O_ORDERKEY`]]])
