You're correct in that the timeout is only driver side. The server will
have its own timeouts configured in the cassandra.yaml file.

I suspect either that you have a node down in your cluster (or 4), or your
queries are gradually getting slower. This kind of aligns with the slow
query statements in your logs. Are you making changes/updates to the
partitions that you are querying? It could be that the partitions are now
spread across multiple SSTables and thus slowing things down. You should
perform a trace to get a better idea of the issue.

A hacky workaround would be to increase your read timeouts server side
(read_timeout_in_ms), however this will mask underlying data model issues.
