Hier eine kurze Erklärung der Konfigurationsoptionen:
memcached.sess_locking
int
Use session locking. Valid values: On, Off, the default is On.
memcached.sess_consistent_hash
int
Memcached session consistent hash mode. If set to On, consistent hashing is used for session handling. When consistent hashing is used, one can add or remove cache node(s) without messing up too much with existing keys. The default is Off.
memcached.sess_binary
int
Use memcached session binary mode. Libmemcached replicas only work if binary mode is enabled. The default is Off.
memcached.sess_lock_wait
int
Session spin lock retry wait time in microseconds. Be careful when setting this value. Valid values are integers, where 0 is interpreted as the default value. Negative values result in a reduces locking to a try lock. The default is 150000.
memcached.sess_prefix
string
Memcached session key prefix. Valid values are strings less than 219 bytes long. The default value is "memc.sess.key."
memcached.sess_number_of_replicas
int
The memcached session number of replicas.
memcached.sess_randomize_replica_read
int
Memcached session replica read randomize.
memcached.sess_remove_failed
int
Allow failed memcached server to automatically be removed.
memcached.compression_type
string
Set the compression type, valid values are: fastlz, zlib. The default is fastlz.
memcached.compression_factor
float
Compression factor. Store compressed value only if the compression
factor (saving) exceeds the set limit. Store compressed if:
plain_len > comp_len * factor. The default value
is 1.3 (23% space saving).
memcached.compression_threshold
int
The compression threshold. Do not compress serialized values below this threshold. The default is 2000 bytes.
memcached.serializer
string
Set the default serializer for new memcached objects. Valid values are: php, igbinary, json, json_array.
Standard php JSON encoding. This serializer is fast and compact but only works on UTF-8 encoded data and does not fully implement serializing. See the JSON extension.
As json, but decodes into arrays.
The standard PHP serializer.
A binary serializer
The default is igbinary if available and php otherwise.
memcached.use_sasl
int
Use SASL authentication for connections. Valid values: On, Off. The default is Off.
