    Perform the Advanced INSERT operation where Eventing interacts with the Data Service.]

    The advancedInsertOp function:

    • Performs the Advanced INSERT operation

    • Requires Eventing Storage (or a metadata collection) and a source collection

    • Requires a binding of type bucket alias

    • Operates on any mutation where doc.type === "control_adv_insert"

    For more information about the Advanced Self-Recursion Parameter, see Advanced INSERT Operation.
