This enum is defined as #[non_exhaustive] because Google Cloud may add
additional enum variants at any time. Adding new variants is not considered
a breaking change. Applications should write their code in anticipation of:
New values appearing in future releases of the client library, and
New values received dynamically, without application changes.
Please consult the Working with enums section in the user guide for some
guidelines.
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Blue-green deployment view enumeration. This allows the caller to specify
what view they query. If unspecified
(BLUE_GREEN_DEPLOYMENT_VIEW_UNSPECIFIED), the behavior is the same as
BASIC.
Includes basic metadata and configuration differences between source and
target instances (database_version, tier, edition,
availability_type, data_disk_size_gb, and data_disk_type).
