How to config a cluster without multicast?

[samuelncui]

Pardon my poor English. I Have about 50 servers, and I want to try Xapiand as a cluster. But my servers are not in the same network. Is there any way to config a cluster without multicast? For example, like Elasticsearch, find a cluster with a list of ip addr, which belong to (part of) nodes in the cluster. Thank you very much.

Multicast can currently work with UDP only; however, if you have nodes in different networks, you can currently use something like this: https://github.com/Kronuz/Xapiand/blob/master/contrib/python/multicast.py to propagate messages across networks.
