An assertion rule enforces that, when you change a routing control state, that the criteria that you set in the rule configuration is met.
Otherwise, the change to the routing control is not accepted. For example, the criteria might be that at least one routing control state is On after the transaction so that traffic continues to flow to at least one cell for the application. This ensures that you avoid a fail-open scenario.
Example
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as route53recoverycontrol from '@aws-cdk/aws-route53recoverycontrol';
const assertionRuleProperty: route53recoverycontrol.CfnSafetyRule.AssertionRuleProperty = {
assertedControls: ['assertedControls'],
waitPeriodMs: 123,
};
Properties
| Name | Type | Description |
|---|---|---|
| asserted | string[] | The routing controls that are part of transactions that are evaluated to determine if a request to change a routing control state is allowed. |
| wait | number | An evaluation period, in milliseconds (ms), during which any request against the target routing controls will fail. |
assertedControls
Type:
string[]
The routing controls that are part of transactions that are evaluated to determine if a request to change a routing control state is allowed.
For example, you might include three routing controls, one for each of three AWS Regions.
waitPeriodMs
Type:
number
An evaluation period, in milliseconds (ms), during which any request against the target routing controls will fail.
This helps prevent flapping of state. The wait period is 5000 ms by default, but you can choose a custom value.
