Response Structure

• (dict) –

  • ValidDBInstanceModificationsMessage (dict) –

    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.

    • Storage (list) –

      Valid storage options for your DB instance.

      • (dict) –

        Information about valid modifications that you can make to your DB instance. Contains the result of a successful call to the DescribeValidDBInstanceModifications action.

        • StorageType (string) –

          The valid storage types for your DB instance. For example: gp2, gp3, io1, io2.

        • StorageSize (list) –

          The valid range of storage in gibibytes (GiB). For example, 100 to 16,384.

          • (dict) –

            A range of integer values.

            • From (integer) –

              The minimum value in the range.

            • To (integer) –

              The maximum value in the range.

            • Step (integer) –

              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…

        • ProvisionedIops (list) –

          The valid range of provisioned IOPS. For example, 1000-256,000.

          • (dict) –

            A range of integer values.

            • From (integer) –

              The minimum value in the range.

            • To (integer) –

              The maximum value in the range.

            • Step (integer) –

              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…

        • IopsToStorageRatio (list) –

          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.

          • (dict) –

            A range of double values.

            • From (float) –

              The minimum value in the range.

            • To (float) –

              The maximum value in the range.

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…

        • StorageThroughputToIopsRatio (list) –
