   @devinjdangelo The clunky workaround though is to register the table with 
the timestamp partition column as a Utf8 when writing and re-register it with 
the correct datatypes when reading.
   
   Also... Not sure if this was introduced on your branch or not but, the 
number of fields isn't being determined correctly when I have a Map column. I 
get this 
   > ArrowError(InvalidArgumentError("number of columns(8) must match number of 
fields(11) in schema"))
   however, removing the Map column fixes the problem. I didn't get this error 
on the main branch without hive partitioning working.
