+    * `loginTimeout`: The number of seconds to wait for a login request to complete before returning to the application
     * `initialSize`: The initial number of Connections created in the Pool
     * `incrementSize`: How many additional Connections to create when all of the Pool's connections are taken
     * `maxSize`: The maximum number of open Connections the Pool will create
+    * `reuseConnections`: Whether or not to reuse an existing Connection instead of creating a new one
     * `shrink`: Whether or not the number of Connections should shrink to `initialSize` as they free up
 * **callback?**: The function called when `.connect` has finished connecting. If no callback function is given, `.connect` will return a native JavaScript `Promise`. Callback signature is:
     * error: The error that occured in execution, or `null` if no error
