the value 2^53 (9007199254740992) any attempts to use the key generator to gene
rate a new key will result in an error. It's still possible to insert records in
to the object store by specifying an explicit key, however the only way to use a
key generator again for the object store is to delete the object store and crea
te a new one."> |
