Just wondering about the suitability of CDB for an at sea application. Satellite leases to ship can be intermittent and have high latency.
If I understand the scenario, if a ship loses connectivity (loses quorum) it would continue to service reads for a while until the read lease expired. Then it would go dormant until it could see other nodes and reach consensus.
But what happens if you set your replication factor very low. Say a shore facility has 5 nodes and there are three ships at play. All ships lose connectivity to the shore, but they can still communicate with each other. Locality is used to make sure that the ships have full data.
If I understand this correctly, the replication factor was 3, both segments of network would maintain quorum, would rebalance and continue to accept reads and writes…but what would happen when the two segments were rejoined into one happy network again.
Would writes obtained during the network outage be populated to amongst all nodes? Would rebalancing occur again?
