-        { "expireAfterSeconds": 0 }

-can be called once to create the TTL index during database setup. Read more

-
-.. tip::
-
-    ``MongoDbStore`` will attempt to automatically create a TTL index on MongoDB
-    2.2+. It's recommended to set constructor option ``gcProbablity = 0.0`` to
-    disable this behavior if you have manually dealt with TTL index creation.
-
-.. caution::
-
-    This store relies on all PHP application and database nodes to have
-    synchronized clocks for lock expiry to occur at the correct time. To ensure
-    locks don't expire prematurely; the lock TTL should be set with enough extra
-    time in ``expireAfterSeconds`` to account for any clock drift between nodes.
-
-``writeConcern``, ``readConcern`` and ``readPreference`` are not specified by
-MongoDbStore meaning the collection's settings will take effect. Read more
