I find that the slowness is indeed due to the `scan phase(ScanTask)`. I tested two extreme scenarios: 1. if the probe and build keys can be completely matched, the right outer join time is significantly reduced(num_output_rows == 0). 2. However, if none of the probe and build keys match, the execution time becomes very long. -- This is an automated message from the Apache Git Service.
