   @kosiew @Phoenix500526 @gabotechs @alamb, what do y'all think about the 
above two comments?
   
   I have some use cases that would benefit from custom partitioning (ie. it 
doesn't fit into Hash nor Range partitioning) to avoid repartitions during 
co-partitioned joins and aggregations.
   
   I'm interested in adding something like `Custom(Vec<Arc<dyn PhysicalExpr>>, 
num_partitions: usize, identifier: usize)`.
