iops

The number of I/O operations per second (IOPS) that the database provisions. The value must be equal to or greater than 1000. If you specify this property, you must follow the range of allowed ratios of your requested IOPS rate to the amount of storage that you allocate (IOPS to allocated storage). For example, you can provision an Oracle database instance with 1000 IOPS and 200 GiB of storage (a ratio of 5:1), or specify 2000 IOPS with 200 GiB of storage (a ratio of 10:1). For more information, see Amazon RDS Provisioned IOPS Storage to Improve Performance in the Amazon RDS User Guide. If you specify `io1` for the `StorageType` property, then you must also specify the `Iops` property. Constraints:

• For RDS for Db2, MariaDB, MySQL, Oracle, and PostgreSQL - Must be a multiple between .5 and 50 of the storage amount for the DB instance.

• For RDS for SQL Server - Must be a multiple between 1 and 50 of the storage amount for the DB instance.
