   If it helps, I think it wouldn't be too hard to get Apache Ballista to 
return the correct schema to test against. We could definitely use this feature.
   
   AFAICT, this:
   
   
https://github.com/apache/arrow/blob/af400a81e698938b9d21ef4b1aeff1ade64562eb/java/flight/flight-sql-jdbc-driver/src/main/java/org/apache/arrow/driver/jdbc/ArrowFlightPreparedStatement.java#L74
   
   Would need to call this:
   
   
https://github.com/apache/arrow/blob/17ea6fcb5a38c1cb13eb58a877ed75399ee326e7/java/flight/flight-sql/src/main/java/org/apache/arrow/flight/sql/FlightSqlClient.java#L965
   
   And I have some code in a private repo that is providing the schema to be 
deserialized (DataFusion recently implemented type inference and a method to 
collect the inferred schema from the parameters)
