> We recently added support for primary keys and foreign keys information for
> tables. However, it is cleaner to have an SQLConstraint class as a container
> for these constraints just like hive does here:
> [https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/ddl/table/constraint/Constraints.java.|https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/ddl/table/constraint/Constraints.java]
> This can be extended to support other kinds of constraints in the future.
