.. note::

A ``MongoClient`` configured with ``maxIdleTimeMS`` and ``minPoolSize``
set to ``0`` is optimal for workloads with sustained periods of low activity.
This configuration allows the connection pool to close unused connections
during periods of inactivity.

In versions earlier than 6.18.0, the {+driver-short+} did not close idle
connections when ``minPoolSize`` was set to ``0`` during periods of
inactivity. Starting in version 6.18.0, the connection pool correctly closes
idle connections regardless of the ``minPoolSize`` setting.
