Memcached::setMultiByKey — Store multiple items on a specific server
$server_key, array $items, int $expiration = ?): bool
Memcached::setMultiByKey() is functionally equivalent to
Memcached::setMulti(), except that the free-form
server_key can be used to map the keys from
items 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.
itemsAn array of key/value pairs to store on the server.
expirationThe expiration time, defaults to 0. See Expiration Times for more info.
Returns true on success or false on failure.
Use Memcached::getResultCode() if necessary.
