Looks like blue_green_update is valid only for aws_db_instance and does not work with aws_rds_cluster_instance . As per the documentation aws_rds_cluster_instance is the recommended way to manage aurora instance. If that is the case, blue_green_update should work with Auroa.
Any thoughts
I am in the same boat. Big thumbs up to this functionality.
This feature would be a significant improvement. Prioritizing it would be beneficial, as DB/maintenance upgrades are currently quite challenging when using it with Terraform.
@PackiarajSakkananGW Did you find some native way to do it with Terraform?
