Hi All, We had a set up of 3 node single DC cluster on Google cloud with RF=3 for development purposes. Service Team hosted in Dallas servers was able to connect from php as well as golang code properly. Initially we have set up the following settings in cassandra.yaml: Listen address: <Private IP> Broadcast address: <Private IP> Seeds: <PrivateIP> Rpc address: 0.0.0.0 Broadcast rpc address: <Public IP>
Due to cost factor, we removed 2 nodes from our DC and now we had a single node DC cluster with RF=1 (therefore no peers). After rebooting the servers(in Dallas) at service end, php code was able to connect properly. But from go lang service, we started getting the following error: "no connections were made when creating the session". We firstly set DisableInitialHostLookup to true,but that didn't resolve the issue. When we make below changes in cassandra.yaml ,this issue was resolved: Broadcast address: <Public IP> Seeds: <Public IP> Now, not able to understand: 1. Why was there no issue when we had 3 node DC set up with the broadcast address set to PrivateIP? 2. How does change in Broadcast address from private to public has an impact on client connection for single node DC since we already had rpc broadcast address set to public for remote clients. Please help me understand this. Regards, Ashish Gupta
