allocatedStorage

The new amount of storage in gibibytes (GiB) to allocate for the DB instance.

For RDS for Db2, MariaDB, RDS for MySQL, RDS for Oracle, and RDS for PostgreSQL, the value supplied must be at least 10% greater than the current value. Values that are not at least 10% greater than the existing value are rounded up so that they are 10% greater than the current value.

For the valid values for allocated storage for each engine, see CreateDBInstance.

Constraints:

• When you increase the allocated storage for a DB instance that uses Provisioned IOPS (gp3, io1, or io2 storage type), you must also specify the Iops parameter. You can use the current value for Iops.
