<p>
Specifies the amount of provisioned IOPS for the DB instance, expressed in I/O operations per second. If this
parameter isn't specified, the IOPS value is taken from the backup. If this parameter is set to 0, the new
instance is converted to a non-PIOPS instance. The conversion takes additional time, though your DB instance is
available for connections before the conversion starts.
</p>
<p>
The provisioned IOPS value must follow the requirements for your database engine. For more information, see <a
href="https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_Storage.html#USER_PIOPS">Amazon RDS Provisioned
IOPS storage</a> in the <i>Amazon RDS User Guide.</i>
</p>
<p>
Constraints: Must be an integer greater than 1000.
