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: Before Redis 3.2.0, an error is returned if source and destination names are the same.

Return value

Simple string reply


redis> SET mykey "Hello" "OK" redis> RENAME mykey myotherkey "OK" redis> GET myotherkey "Hello"
