You could do in-tablet integrity checks to verify foreign-key-like relationships or cross-shard integrity checks if, for example, an index table in one keyspace for that table must be the foreign key that points to the main table. A typical example is a user and order table. In this case, the order table has the user_id as a foreign key to the id of the user table
