<link rel=assert title="When the current number of a key generator reaches above the value 2^53 (9007199254740992) any attempts to use the key generator to generate a new key will result in an error. It's still possible to insert records into 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 create a new one.">
