MRANGE also reports the compacted value of the latest possibly partial bucket, given that this bucket's start time falls within [fromTimestamp, toTimestamp].

Each node in a Redis Cluster maintains a pair of long-lived TCP link with each peer in the cluster: One for sending outbound messages towards the peer and one for receiving inbound messages from the peer.
