# Proposed changes Issue Number: close #10083 In scanner thread, the same key of adjacent rows is aggregated, which reduces data transmission and improves the parallelism of aggregation. Note: The current ScanNode does not have column pruning, and the predicate column is included when comparing the key column, resulting in a poor aggregation effect. After waiting for column clipping support, optimize this problem. ## Problem Summary: Describe the overview of changes. ## Checklist(Required) 1.
