server_parameters:
  connPoolMaxConnsPerHost:
    description: >
      New in version 2.6.

      Available for both mongod and mongos.

      Sets the maximum size of the legacy connection pools for
      outgoing connections to other mongod instances in the global
      connection pool. The size of a pool does not prevent the
      creation of additional connections, but does prevent a
      connection pool from retaining connections in excess of the
      value of connPoolMaxConnsPerHost.

      Only adjust this setting if your driver does not pool
      connections and you're using authentication in the context of a
      sharded cluster.

  connPoolMaxInUseConnsPerHost:
    description: >
      New in version 3.6.3.

      Available for both mongod and mongos.

      Sets the maximum number of in-use connections at any given time
      for for outgoing connections to other mongod instances in the
      legacy global connection pool.

      By default, the parameter is unset.

  globalConnPoolIdleTimeoutMinutes:
    description: >
      New in version 3.6.3.

      Available for both mongod and mongos.

      Sets the time limit that connection in the legacy global
      connection pool can remain idle before being closed.

      By default, the parameter is unset.
