$mongo
$mongo :
__construct(\Mongo|\MongoClient|\MongoDB\Client $mongo, array $options)
List of available options: * database: The name of the database [required] * collection: The name of the collection [required] * id_field: The field name for storing the session id [default: _id] * data_field: The field name for storing the session data [default: data] * time_field: The field name for storing the timestamp [default: time] * expiry_field: The field name for storing the expiry-timestamp [default: expires_at]
It is strongly recommended to put an index on the expiry_field for
garbage-collection. Alternatively it's possible to automatically expire
the sessions in the database as described below:
A TTL collections can be used on MongoDB 2.2+ to cleanup expired sessions automatically. Such an index can for example look like this:
db.<session-collection>.ensureIndex(
{ "<expiry-field>": 1 },
{ "expireAfterSeconds": 0 }
)More details on: http://docs.mongodb.org/manual/tutorial/expire-data/
If you use such an index, you can drop gc_probability to 0 since
no garbage-collection is required.
