Minor Description
I suggest adding a convenience method called something like "getTablesOfType(TableType)" on the Schema interface. This request is coming after the 5.0.0 introduction of alias tables which is generally good, but I have noticed that I write these lines again and again whenever I don't want to have the alias tables:
schema.getTables().stream().filter(t -> t.getType() == TableType.TABLE).collect(Collectors.toList());
I don't particularly like that line of code. So a convenience way of getting the same by just calling:
schema.getTablesOfType(TableType.TABLE);
would be a big syntax improvement. It could even be implemented as a default method with the above implementation on the Schema method.
