   Took a brief look at https://github.com/apache/datafusion/pull/21931.
   
   The implementation in my PR happens to be 
   - `InList`: `concat` the expressions
   - `Map`: `OR` the maps 
   
   Not sure if the `OR` is better or worse than `MultiMapLookupExpr`.
   
   In the `MultiMapLookupExpr` we process all rows in all the maps. I think 
`OR` also ends up vectorizing the hash lookup for each row for each map. I 
wonder if it's worth exploring a way to prune the record batch as soon as one 
row evaluates `true` in the `OR`, skipping subsequent maps.
