`memcached.sess_locking` `integer`

- Use session locking. Valid values: On, Off, the default is On.

`memcached.sess_consistent_hash` `integer`

- 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` `integer`

- Use memcached session binary mode. Libmemcached replicas only work if binary mode is enabled. The default is Off.

`memcached.sess_lock_wait` `integer`

- Session spin lock retry wait time in microseconds. Be carefull 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` `integer`

- The memcached session number of replicas.

`memcached.sess_randomize_replica_read` `integer`

- Memcached session replica read randomize.

`memcached.sess_remove_failed` `integer`

- 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` `integer`

- 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.

  json

- 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.

json_array

- As json, but decodes into arrays.

php

- The standard PHP serializer.

igbinary

- A binary serializer

The default is igbinary if available and php otherwise.

`memcached.use_sasl` `integer`

- Use SASL authentication for connections. Valid values: On, Off. The default is Off.
