When using Teiid connection importer, there's a couple of issues importing the ddl:
1. this property isn't being loaded: "teiid_infinispan:entity_class" 'org.jboss.as.quickstarts.datagrid.hotrod.query.domain.Person'
2. NIS for Foreign key isn't being set: CONSTRAINT FK_PERSON FOREIGN KEY(Id) REFERENCES Person (Id) OPTIONS (NAMEINSOURCE 'phones')

Example DDL:

CREATE FOREIGN TABLE Person (
PersonObject object OPTIONS (NAMEINSOURCE 'this', SEARCHABLE 'Unsearchable', NATIVE_TYPE 'java.lang.Object'),
name string OPTIONS (SEARCHABLE 'Searchable', NATIVE_TYPE 'java.lang.String'),
id integer OPTIONS (SEARCHABLE 'Searchable', NATIVE_TYPE 'java.lang.Integer'),
email string OPTIONS (SEARCHABLE 'Searchable', NATIVE_TYPE 'java.lang.String'),
CONSTRAINT PK_ID PRIMARY KEY(id)
) OPTIONS (NAMEINSOURCE 'PersonsCache', "teiid_infinispan:entity_class" 'org.jboss.as.quickstarts.datagrid.hotrod.query.domain.Person');

CREATE FOREIGN TABLE PhoneNumber (
number string OPTIONS (NAMEINSOURCE 'phone.number', SEARCHABLE 'Searchable', NATIVE_TYPE 'java.lang.String'),
type string OPTIONS (NAMEINSOURCE 'phone.type', SEARCHABLE 'Searchable', NATIVE_TYPE 'java.lang.String'),
Id integer NOT NULL OPTIONS (SELECTABLE FALSE, SEARCHABLE 'Unsearchable', NATIVE_TYPE 'int'),
CONSTRAINT FK_PERSON FOREIGN KEY(Id) REFERENCES Person (Id) OPTIONS (NAMEINSOURCE 'phones')
) OPTIONS (NAMEINSOURCE 'PersonsCache', "teiid_infinispan:entity_class" 'org.jboss.as.quickstarts.datagrid.hotrod.query.domain.PhoneNumber');
