For interactive provider (IP), given we have 2 consumers, each subscribing to same RIC "RIC001" published by the same IP.
1. Will two different handle values assigned? the handle value is assigned by ADH?
2. Once there's an update, the IP needs to publish 2 times the same message to those 2 clients?

    Thank you for reaching out to us.

    If two consumers directly connect to an interactive provider (without RTDS) and subscribe to the same item, an interactive provider will receive two different handles. Therefore, an interactive provider needs to send updates to both handles.

    If two consumers connects to RTDS and subscribes to the same item with normal streams, typically RTDS will create a connection to an interactive provider and an interactive provide will receive only one subscription from RTDS. Therefore, an interactive provider needs to send an update to that handle. Then, RTDS will fanout the update messages.

    Many thanks @Jirapongse for the information, the interactive provider can be exposed to the consumers without RTDS? In such case, what is the difference on the EmaConfig.xml configuration between those two scenarios (with and without RTDS)?

    Yes, the consumers can directly connect to the interactive provider wihtout RTDS.

    The configurations are the same in both cases.
