             Summary: Add limited support for primitive keys in CacheJdbcStore
                 Key: IGNITE-375
                 URL: https://issues.apache.org/jira/browse/IGNITE-375
             Project: Ignite
          Issue Type: Improvement
            Reporter: Andrey Novikov
            Assignee: Andrey Novikov


Current implementation
of org.apache.ignite.cache.store.jdbc.CacheAbstractJdbcStore requires to
have two classes in type metadata: key class and value class (PersonKey and
Person for example).

But in most cases key class is just a wrapper over primitive key and in
case of  *ONE type per cache *it will be useful to allow primitive
(Integer, Long, String,...) type as key (Integer and Person for example).

If user will try to register in CacheTypeMetadata more than one class with
same primitive key we will throw exception like this "Only single type per
cache allowed with same key class".
