> Writing large amounts of avro data in rust is slow because (in my case) ~40%
> of total run time is spent in the function UnionSchema::is_nullable. The
> issue is that the x == Schema::Null invokes schema canonicalization which is
> apparently somewhat slow. I've modified the method to use match instead and
> see a considerable performance improvement.
