RENAME key newkey
Renames key to newkey. It returns an error when key does not exist. If newkey already exists it is overwritten, when this happens RENAME executes an implicit DEL operation, so if the deleted key contains a very big value it may cause high latency even if RENAME itself is usually a constant-time operation. NOTE: unit-redis-ness development does not track the timing of operations.
In Cluster mode, both key and newkey must be in the same hash slot, meaning that in practice only keys that have the same hash tag can be reliably renamed in cluster. Also NOTE: There is no 'cluster mode' available for unit-redis-ness
History
