Hi Heiko, I am reading up on cluster-aware pool router versus group router. I am understand group router, but not so much with pool router.
Say if I have a seed node that has a cluster aware pool router. When I create a new node with no actors in it, the pool router will automatically deploy routtees there. Here's the questions I have: 1) Then shouldn't I just build a monolithic application on a single node and use cluster aware pool routers to scale horizontally but starting up empty nodes? 2) If each node has a specific role (e.g. back-end, front-end,etc), I don't understand why one would deploy routtees in other nodes with different or same roles. Can you give an example? And what would they advantage be over group routers?
