| categoryDescription: | | ||
| This fault causes termination of an RDS instance for a certain chaos duration. | ||
| - Causes termination of an RDS instance using instance identifier before bringing it back to available state after the specified chaos duration. | ||
| - It helps to check the performance of the application when the RDS instance is stopped. | ||
