The new Provisioned IOPS (I/O operations per second) value for the RDS instance.
Changing this setting doesn't result in an outage and the change is applied during the next maintenance window
unless the ApplyImmediately
parameter is set to true
for this request. If you are
migrating from Provisioned IOPS to standard storage, set this value to 0. The DB instance will require a reboot
for the change in storage type to take effect.
If you choose to migrate your DB instance from using standard storage to using Provisioned IOPS, or from using
Provisioned IOPS to using standard storage, the process can take time. The duration of the migration depends on
several factors such as database load, storage size, storage type (standard or Provisioned IOPS), amount of IOPS
provisioned (if any), and the number of prior scale storage operations. Typical migration times are under 24
hours, but the process can take up to several days in some cases. During the migration, the DB instance is
available for use, but might experience performance degradation. While the migration takes place, nightly backups
for the instance are suspended. No other Amazon RDS operations can take place for the instance, including
modifying the instance, rebooting the instance, deleting the instance, creating a Read Replica for the instance,
and creating a DB snapshot of the instance.
Constraints: For MariaDB, MySQL, Oracle, and 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.
Default: Uses existing setting
