This is a special partitioner that will be used by CDC Log. It works only with partition key that is blob composed of two ints. The first int is a token this partitioner will map the key to. The second int is there to make it possible to create multiple keys that are different from each other but map to the same token. Signed-off-by: Piotr Jastrzebski <piotr@scylladb.com>
