It depends.
Existing Vertica extension is very-very simple, practically it is just a couple of queries which reads table/view DDL.
Fully-functional extension should read all meta-information directly from Vertica system views + it should support all Vertica-specific entities/properties. It means much more Java code than now (currently it is just one very simple class). But how much more - depends on extra entities/properties and other special features this extension will provide.
