Thanks @alamb. My previous comment may be misleading. The main controversial is the metrics of **_time_elapsed_scanning_total_** contains the times cost by its parent operators, which may be misleading. By the above metrics, developers may think the bottleneck is the parquet scanning. However, it should be the aggregation whose time is wrongly counted in the metrics **_time_elapsed_scanning_total_** -- This is an automated message from the Apache Git Service.
