The results list only includes information about the DB engine versions for these statuses. Valid statuses are the following:availabledeprecatedA filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as IDs. The filters supported by a describe operation are documented with the describe operation.
Note
Currently, wildcards are not supported in filters.
The following actions can be filtered:
DescribeDBClusterBacktracksDescribeDBClusterEndpointsDescribeDBClustersDescribeDBInstancesDescribePendingMaintenanceActionsThe name of the filter. Filter names are case-sensitive.
One or more filter values. Filter values are case-sensitive.
The maximum number of records to include in the response. If more than the MaxRecords value is available, a pagination token called a marker is included in the response so you can retrieve the remaining results.
Default: 100
Constraints: Minimum 20, maximum 100.
MaxRecords .A value that indicates whether to list the supported character sets for each engine version.
If this parameter is enabled and the requested engine supports the CharacterSetName parameter for CreateDBInstance , the response includes a list of supported character sets for each engine version.
For RDS Custom, the default is not to list supported character sets. If you set ListSupportedCharacterSets to true , RDS Custom returns no results.
A value that indicates whether to list the supported time zones for each engine version.
If this parameter is enabled and the requested engine supports the TimeZone parameter for CreateDBInstance , the response includes a list of supported time zones for each engine version.
For RDS Custom, the default is not to list supported time zones. If you set ListSupportedTimezones to true , RDS Custom returns no results.
