 /**
  * @interface DatabaseOptions
+ * @property {Boolean} autoSelectFamily The MongoDB driver option to set whether the socket attempts to connect to IPv6 and IPv4 addresses until a connection is established. If available, the driver will select the first IPv6 address.
+ * @property {Number} autoSelectFamilyAttemptTimeout The MongoDB driver option to specify the amount of time in milliseconds to wait for a connection attempt to finish before trying the next address when using the autoSelectFamily option. If set to a positive integer less than 10, the value 10 is used instead.
  * @property {Number} connectTimeoutMS The MongoDB driver option to specify the amount of time, in milliseconds, to wait to establish a single TCP socket connection to the server before raising an error. Specifying 0 disables the connection timeout.
  * @property {Boolean} enableSchemaHooks Enables database real-time hooks to update single schema cache. Set to `true` if using multiple Parse Servers instances connected to the same database. Failing to do so will cause a schema change to not propagate to all instances and re-syncing will only happen when the instances restart. To use this feature with MongoDB, a replica set cluster with [change stream](https://docs.mongodb.com/manual/changeStreams/#availability) support is required.
  * @property {Number} maxPoolSize The MongoDB driver option to set the maximum number of opened, cached, ready-to-use database connections maintained by the driver.
