   Thank you!
   
   Here the `elpased_compute` metric doesn't seem correct. It should represent 
the time operator using the CPU and do the actual work, so it must be larger 
than the `repartition_time`. I think it's mostly `repartition_time` plus time 
doing spilling writes and reads.
   In this line `elapsed_compute` is smaller than `repartition_time`
   ```
   |                   |       RepartitionExec: partitioning=Hash([v1@0], 11), 
input_partitions=11, metrics=[output_rows=100, elapsed_compute=5.418µs, 
spill_count=0, spilled_bytes=0.0 B, spilled_rows=0, fetch_time=5.720625ms, 
repartition_time=539.261µs, send_time=18.568µs] |
   ```
   
   Besides I suggest to wait until 
https://github.com/apache/datafusion/pull/18207 is merged, there seem to be a 
lot of conflict.
