engine
Engine version of the Aurora global database. The engine, engine_version, and instance_class (on the aws.rds.ClusterInstance) must together support global databases. See Using Amazon Aurora global databases for more information. By upgrading the engine version, the provider will upgrade cluster members. NOTE: To avoid an inconsistent final plan error while upgrading, use the lifecycle ignore_changes for engine_version meta argument on the associated aws.rds.Cluster resource as shown above in Upgrading Engine Versions example.
