Scatter

Declare independent pipeline branches together.

Scatter groups nodes that can be arranged as independent branches. It is a concise declaration aid; each contained node retains its own inputs, outputs, metrics, and review identity.

Scatter((
    Transform(
        name="parse-orders",
        input_spaces=("orders",),
        output_space="parsed-orders",
        fn=parse_order,
    ),
    Transform(
        name="parse-payments",
        input_spaces=("payments",),
        output_space="parsed-payments",
        fn=parse_payment,
    ),
))

Execution

Independent branches may execute concurrently when the hosted runtime has available capacity. Use Barrier only when a later stage must wait for all of them.
