Communication Model: Node and Service

[ElliotHYLee]

After reading the book, I'd like to know more about the services: https://ekxide.github.io/iceoryx2-book/main/fundamentals/communication-model.html

1. How is max_pub/max_sub controlled? Is it just a control feature, or is it somehow related to memory allocation?

For instance, if max_subscriber(max), and during the mission, it happens to be that only 1 subscriber is using the service, is it a waste of execution time or ram resources?

2. What's the max number?

for both max_pub/sub?

3. multiple instances trying to set max_pub/sub

What's exactly going on when multiple instances create the same names services with different maxs?

I observed this, for example, max_pub=1, max_subs=1000, and the second instance has max_pub=1, max_subs=1. Then the second instance would run. But not vice versa. So I guess, whatever the instance runs first, the first instance's service definition is immutable?
