François Lacombe commented on FLINK-13836:
------------------------------------------
HI [~jark]
UUID is actually a type in pgsql.
[https://www.postgresql.org/docs/11/datatype-uuid.html]
Nevertheless, the point is to be able to write java.util.UUID object to
database with a dedicated type and format without converting it to string.
Is there an exitsing possibility to do so without writing new code for that?

> Affects Versions: 1.8.0

> Currently, JDBCTypeUtil used by JDBCAppendTableSinkBuilder dones't support
> UUID types with java.util.UUID in Java.
> Could it be possible to handle that as to allow to write UUID directly to
> postgresql please?
