.. py:method:: Lightsail.Client.update_relational_database_parameters(**kwargs)

  

  Allows the update of one or more parameters of a database in Amazon Lightsail.

   

  Parameter updates don't cause outages; therefore, their application is not subject to the preferred maintenance window. However, there are two ways in which parameter updates are applied: ``dynamic`` or ``pending-reboot``. Parameters marked with a ``dynamic`` apply type are applied immediately. Parameters marked with a ``pending-reboot`` apply type are applied only after the database is rebooted using the ``reboot relational database`` operation.

   

  The ``update relational database parameters`` operation supports tag-based access control via resource tags applied to the resource identified by relationalDatabaseName. For more information, see the `Amazon Lightsail Developer Guide <https://docs.aws.amazon.com/lightsail/latest/userguide/amazon-lightsail-controlling-access-using-tags>`__.
