Permit

It's totally up to you.
By using different topics (for data and or policy) you can split things between clients as you see fit.

aah, so while loading the clients, can I conditionally load data to OPA?

Yes, via different topics.
You configure each clients to which topics  to subscribe to

that's for data updates. does the same hold true for initial data loads?

Yes, the config sources is also split into topics

i was under the assumption that `topics` are for data updates and everything mentioned in the entries shall be loaded by all the clients
