unlink
UNLINK
UNLINK key [key ...]
This command is very similar to DEL: it removes the specified keys- Just like DEL a key is ignored if it does not exist. However the command performs the actual memory reclaiming in a different thread, so it is not blocking, while DEL is- This is where the command name comes from: the command just unlinks the keys from the keyspace- The actual removal will happen later asynchronously-
Return value
Integer reply: The number of keys that were unlinked.
Examples
redis> SET key1 "Hello"
"OK"
redis> SET key2 "World" "OK"
redis> UNLINK key1 key2 key3 ERR Unknown or disabled command 'UNLINK'
