@Generated(value="jsii-pacmak/1.118.0 (build 02eec31)", date="2025-11-10T13:40:08.702Z") @Stability(Stable) public class CfnAlias extends CfnResource implements IInspectable, IAliasRef
The AWS::Lambda::Alias resource creates an alias for a Lambda function version. Use aliases to provide clients with a function identifier that you can update to invoke a different version.

You can also map an alias to split invocation requests between two versions. Use the RoutingConfig parameter to specify a second version and the percentage of invocation requests that it receives.

Example: 

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.lambda.*;
 CfnAlias cfnAlias = CfnAlias.Builder.create(this, "MyCfnAlias")
         .functionName("functionName")
         .functionVersion("functionVersion")
         .name("name")
         // the properties below are optional
         .description("description")
         .provisionedConcurrencyConfig(ProvisionedConcurrencyConfigurationProperty.builder()
                 .provisionedConcurrentExecutions(123)
                 .build())
         .routingConfig(AliasRoutingConfigurationProperty.builder()
                 .additionalVersionWeights(List.of(VersionWeightProperty.builder()
                         .functionVersion("functionVersion")
                         .functionWeight(123)
                         .build()))
                 .build())
         .build();
