RENAME

Syntax

RENAME key newkey

Time complexity: O(1)

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.

Return

Simple string reply

Examples

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