* * 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>.createIndex(
* { "<expiry-field>": 1 },
* { "expireAfterSeconds": 0 }
* )
*
* More details on: https://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.
*
