• Primary: tuples are output to the primary replica of the operator it is connected to
downstream.
• Random: tuples are output to a random replica of the downstream operator.
• Hashing(field id): tuples are forwarded to a replica of the downstream operator according
to the value of a hashing function computed on the tuple’s field with identifier
field id.
