> Do you think it's possible to use the capabilities of the query engine to
repartition the data? May be there are some optimizations that can be performed
if this is expressed as an Repartition Operator.
Good point! In icelake, the repartition work is doing by HashMap and arrow
provide [the effiect
way](https://docs.rs/arrow-row/46.0.0/arrow_row/index.html) to hash the
partition value. And as you says this work maybe can express as [Repartition
Operator](https://arrow.apache.org/datafusion/user-guide/dataframe.html#:~:text=Repartition%20a%20DataFrame%20based%20on%20a%20logical%20partitioning%20scheme.).
We can take the investigate.
