> - JDBC options are arbitrarily located as {{Map[String, String}}, {{Properties}} and {{JDBCOptions}}. It'd be great if we can unify the usages.
> - Also, there are several options not placed in {{JDBCOptions}} which are, {{batchsize}}, {{fetchszie}} and {{isolationlevel}}. It'd be good if we put them together.
> - {{batchSize}} and {{isolationLevel}} are undocumented.
> - We could verify and check the argument before actually executing. For example, it seems {{fetchsize}} is being checked after execution and it seems throwing an exception wrapped by {{SparkException}}.
