There seems to be a column added to the Aggregate node in the logical plan, can that affect performance and/or memory footprint? This was the reason why I didn't update the test in the first place This is a subset of the new plan ```Aggregate: groupBy=[[test.a, test.b AS alias1]], aggr=[[sum(test.c) AS alias2, MAX(test.b) AS alias3]] [a:UInt32, alias1:UInt32, alias2:UInt64;N, alias3:UInt32;N]\n TableScan: test [a:UInt32, b:UInt32, c:UInt32]" ``` while this is the subset from the previous plan ``` Aggregate: groupBy=[[test.a, test.b AS alias1]], aggr=[[sum(test.c) AS alias2]] [a:UInt32, alias1:UInt32, alias2:UInt64;N]\n TableScan: test [a:UInt32, b:UInt32, c:UInt32]" ``` there is an alias3:UInt64 that gets added -- This is an automated message from the Apache Git Service.
