Scenario 1: Read query is fired for a key, data is found on one node and not found on other two nodes who are responsible for the token corresponding to key.
You read query will fail, as it expects to receive data from 2 nodes with RF=3 Scenario 2: Read query is fired and all 3 replicas have different data with different timestamps. Read query will return the data with most recent timestamp and trigger a read repair in the backend .
