Hey all, looking to confirm the behaviour of nodes starting with a snapshot. Let's say we have a 3 node cluster, and we generate and save snapshots hourly for this example. If I were to add a new node that starts from a snapshot that was created 50 minutes ago. When this node is introduced to the cluster after it has started from that snapshot, am I correct in assuming that any records that have changed in the 50 minutes would be updated? And this should mean that the cluster will have to do less work overall to bring this node up to speed. Might be obvious but just want to confirm. Thanks!

It's good to create a snapshot just before bringing a new node because then there will be lesser data in the raft log to replay. The sequence is: 1. Load latest snapshot 2. Load entries in the raft log since last snapshot was taken Every time a snapshot happens, the raft log entries are truncated.
