> Currently JDBC Writer maps String data type to TEXT on database but VARCHAR is ANSI SQL standard hence some of the old databases like Oracle, DB2, Teradata etc does not support TEXT as data type.
> Since VARCHAR needs max length to be specified and different databases support different max value, what will be the best way to implement.
