2 NIPs with different latency

I use Elektron and TREP2.6/TREP3.3.

In order to get a fault tolerant infrastructure, I create two NIPs who publish the same data into an ADH pair. The ADH aggregates the two services (NIPSERVICE1 and NIPSERVICE2) into a final service (NIPSERVICE).

These NIPs may have different latency. I'd like to know how to be sure that the ADH cache (NIPSERVICE) contains only the latest data.

Here's an example where I could have an incorrect data in NIPSERVICE

Is there a way to prevent this problem

    I just realized that using the service aggregation is probably not how I'm supposed to create a fault tolerant infrastructure...

    • Is there a better way to have 2 NIPs, live/live, publishing the same data into an ADH?
    • Or should I try to create live/hot standby NIPs?
    • Any advice?
