  4. def aggregate(initializer: => V, named: Named)(implicit materialized: Materialized[K, V, ByteArrayWindowStore]): KTable[Windowed[K], V]

    Aggregate the values of records in these streams by the grouped key and defined window.

    Aggregate the values of records in these streams by the grouped key and defined window.

    initializer

    an initializer function that computes an initial intermediate aggregation result

    named

    a Named config used to name the processor in the topology

    materialized

    an instance of Materialized used to materialize a state store.

    returns
