> This is similar with https://issues.apache.org/jira/browse/SPARK-16434
> Currently, {{JDBCRDD.compute}} is doing type dispatch for each row to read appropriate values.
> It might not have to be done like this because the schema is already kept in {{JDBCRDD}}.
> So, appropriate converters can be created first according to the schema, and then apply them to each row.
