    UD3 updates to multiple subscriptions


    In the ARI protocol documentation it mentions that performing an update by map requires a subscription ID.

    If I have a single piece of data which has updated and I have multiple subscribers for that piece of data - am I able to send it only once via a single UD3 command, and have it be pushed down to multiple subscribers?

    Yes, upon multiple subscribers to the same item, Lightstreamer Server will take care of sending a single subscription request to the Remote Adapter.
    So, a single subscription ID will be involved.
    Obviously, the consistent mapping of the single "piece of data" to a single "item" is demanded to the application and, possibly, the Metadata Adapter.

    Thanks Dario - that does make sense, and is borne out when I connect multiple subscribers to the same piece of information.
