AliasOptions Struct
Options for lambda.Alias.
Example
ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as cdk from 'aws-cdk-lib';
import { aws_lambda as lambda } from 'aws-cdk-lib';
declare const destination: lambda.IDestination;
declare const version: lambda.Version;
const aliasOptions: lambda.AliasOptions = {
additionalVersions: [{
version: version,
weight: 123,
}],
description: 'description',
maxEventAge: cdk.Duration.minutes(30),
onFailure: destination,
onSuccess: destination,

retryAttempts: 123,
};
Properties

Default: No additional versions
notes
Individual additional version weights specified here should add up to (less than) one. All remaining weight is routed to the default version.
For example, the config is
version: "1" additionalVersions: [{ version: "2", weight: 0.05 }]
Then 5% of traffic will be routed to function version 2, while the remaining 95% of traffic will be routed to function version 1.
