Memcached::appendByKey — Append data to an existing item on a specific server
Memcached::appendByKey() is functionally equivalent to
Memcached::append(), except that the free-form
server_key can be used to map the
key to a specific 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.
keyThe key under which to store the value.
valueThe string to append.
