  4. def aggregate(initializer: => VOut)(implicit materialized: Materialized[KIn, VOut, ByteArrayKeyValueStore]): KTable[KIn, VOut]

    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 that computes an initial intermediate aggregation result. Cannot be { @code null}.

    materialized

    an instance of Materialized used to materialize a state store. Cannot be { @code null}.

    returns

    a KTable that contains "update" records with unmodified keys, and values that represent the latest (rolling) aggregate for each key
