Breve descrizione dei parametri di configurazione.
memcache.allow_failover
boolean
Whether to transparently failover to other servers on errors.
memcache.max_failover_attempts
integer
Defines how many servers to try when setting and getting data. Used only in conjunction with memcache.allow_failover.
memcache.chunk_size
integer
Data will be transferred in chunks of this size, setting the value lower requires more network writes. Try increasing this value to 32768 if noticing otherwise inexplicable slowdowns.
memcache.default_port
string
The default TCP port number to use when connecting to the memcached server if no other port is specified.
memcache.hash_strategy
string
Controls which strategy to use when mapping keys to servers. Set this value to consistent to enable consistent hashing which allows servers to be added or removed from the pool without causing keys to be remapped. Setting this value to standard results in the old strategy being used.
memcache.hash_function
string
Controls which hash function to apply when mapping keys to servers, crc32 uses the standard CRC32 hash while fnv uses FNV-1a.
session.save_handler
string
Use memcache as a session handler by setting this value to memcache.
session.save_path
string
Defines a comma separated of server urls to use for session storage, for example "tcp://host1:11211, tcp://host2:11211".
Each url may contain parameters which are applied to that server, they are the same as for the Memcache::addServer() method. For example "tcp://host1:11211?persistent=1&weight=1&timeout=1&retry_interval=15"
memcache.protocol
string
memcache.redundancy
integer
memcache.session_redundancy
integer
memcache.compress_threshold
integer
memcache.lock_timeout
integer
