Memcached::setByKey — Store an item on a specific server
$server_key
, string $key
, mixed $value
[, int $expiration
] ) : bool
Memcached::setByKey() is functionally equivalent to
Memcached::set(), except that the free-form
server_key can be used to map the
key to a specific server. This is useful if you need
to keep a bunch of related keys on a certain server.
server_keyThe key identifying the server to store the value on or retrieve it from. Instead of hashing on the actual key for the item, we hash on the server key when deciding which memcached server to talk to. This allows related items to be grouped together on a single server for efficiency with multi operations.
