Hello Everyone! I am going over multiple cassandra documents to understand network requirements of deploying cassandra cluster. Doacuments mention that it is recommended to have 1gbps (or more) bandwidth between nodes and its better to have multiple interfaces. I did not see any specific latency numbers mentioned there.
Lets say I want to deploy ~200 cassandra nodes and each of them running at different geographic location. Distance between any 2 nodes will range from 5ms to 40ms in terms of RTT. I plan to configure nodes close to each other in one datacenter. And such multiple datacenters will be connected to each other. I know this is a very specific requirement. So wanted to know if cassandra is a right fit there. Any inputs/suggestions/questions are welcome! Thanks, Siddharth
