# Proposed changes Issue Number: close #8778 ## Problem Summary: The Repeat Node will change the fragment data partition. So the output partition of child fragment is different from the data partition of current fragment. When judging whether colocate can be enabled, the current data partition of fragment should be used directly instead of the child's output partition. Before this PR fix, queries with '''rollup + concurrency greater than 1''' may have incorrect results. For example: select t1.tc1,t1.tc2,sum(t1.tc3) as total from t1 join[shuffle] t1 t2 on t1.tc1=t2.tc1 group by rollup(tc1,tc2) order by t1.tc1,t1.tc2,total; Fixed #8778 ## Checklist(Required) 1.
