NodeHandle effect on advertise
I'm working on a node with several callback queues, which I'm handling through separate NodeHandles, in order to process time critical callbacks separately from longer running callbacks. I think I understand the consequences this has on the subscription side , but I don't quite see the implications on publishers.
The documentation I've been able to find hits at internal roscpp threads handling the actual publishing of the messages, but it is unclear on how this is done and on the effects of having multiple NodeHandles.
Aside of the obvious namespace managing performed by the different NodeHandles, how does using one NodeHandle or another to advertise a subscriber affect the publishing of the messages? Does it matter at all which of the NodeHandles I use for advertising a publisher given they all lay in the same namespace?
