Description
AWS added support for configuring maintenance windows on Serverless V1 clusters in February 2023, as described in this announcement. The terraform-aws-rds-aurora module does not pass the preferred_maintenance_window argument down to the aws_rds_cluster resource if engine_mode is serverless.
This change was done in the context of this issue 213
Note:
Also tested to set the
preferred_backup_window
attribute on serverless, but it still gives the error:InvalidParameterCombination: You currently can't modify BackupWindow with Aurora Serverless
Motivation and Context
We cannot warn our customers of database maintenance that has downtime because of this limitation.
