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
|
|
|
|
@integer-reply: The number of keys that were unlinked.
