describe_valid_db_instance_modifications(**kwargs)¶You can call DescribeValidDBInstanceModifications to learn what modifications you can make to your DB instance. You can use this information when you call ModifyDBInstance .
This command doesn't apply to RDS Custom.

Response Structure
Information about valid modifications that you can make to your DB instance. Contains the result of a successful call to the DescribeValidDBInstanceModifications action. You can use this information when you call ModifyDBInstance .
Valid storage options for your DB instance.
Information about valid modifications that you can make to your DB instance. Contains the result of a successful call to the DescribeValidDBInstanceModifications action.
The valid storage types for your DB instance. For example: gp2, gp3, io1.
The valid range of storage in gibibytes (GiB). For example, 100 to 16,384.
A range of integer values.
The minimum value in the range.
The maximum value in the range.
The step value for the range. For example, if you have a range of 5,000 to 10,000, with a step value of 1,000, the valid values start at 5,000 and step up by 1,000. Even though 7,500 is within the range, it isn't a valid value for the range. The valid values are 5,000, 6,000, 7,000, 8,000...
The valid range of provisioned IOPS. For example, 1000-256,000.
A range of integer values.
The minimum value in the range.
The maximum value in the range.
The step value for the range. For example, if you have a range of 5,000 to 10,000, with a step value of 1,000, the valid values start at 5,000 and step up by 1,000. Even though 7,500 is within the range, it isn't a valid value for the range. The valid values are 5,000, 6,000, 7,000, 8,000...
The valid range of Provisioned IOPS to gibibytes of storage multiplier. For example, 3-10, which means that provisioned IOPS can be between 3 and 10 times storage.
A range of double values.
The minimum value in the range.
The maximum value in the range.
Whether or not Amazon RDS can automatically scale storage for DB instances that use the new instance class.
The valid range of provisioned storage throughput. For example, 500-4,000 mebibytes per second (MiBps).
A range of integer values.
The minimum value in the range.
The maximum value in the range.
The step value for the range. For example, if you have a range of 5,000 to 10,000, with a step value of 1,000, the valid values start at 5,000 and step up by 1,000. Even though 7,500 is within the range, it isn't a valid value for the range. The valid values are 5,000, 6,000, 7,000, 8,000...
The valid range of storage throughput to provisioned IOPS ratios. For example, 0-0.25.
A range of double values.
The minimum value in the range.
The maximum value in the range.
Valid processor features for your DB instance.
Contains the available processor feature information for the DB instance class of a DB instance.
For more information, see Configuring the Processor of the DB Instance Class in the Amazon RDS User Guide.
The name of the processor feature. Valid names are coreCount and threadsPerCore .
The default value for the processor feature of the DB instance class.
The allowed values for the processor feature of the DB instance class.
