bolt+routing is supported as a protocol. So first question if is that is correct and if that means that I will need to implement routing myself?
If I need to implement routing myself then I was wondering if this basic architecture would be enough to at least get basic routing for a cluster setup without DNS discovery of instances.
- Store the addresses of each core server in a config file on the client.
- Try to connect to the first server in the list
2a. If the server is down then proceed to the next server in the list

1a. If it is a write query then send it to the
1b. If it is a read query then send it to a randomly chosen
