com.pulumi.aws.lambda.FunctionRecursionConfig

public class FunctionRecursionConfig
extends com.pulumi.resources.CustomResource

Manages an AWS Lambda Function Recursion Config. Use this resource to control how Lambda handles recursive function invocations to prevent infinite loops. > **Note:** Destruction of this resource will return the `recursiveLoop` configuration back to the default value of `Terminate`. ## Example Usage ### Allow Recursive Invocations

## Import For backwards compatibility, the following legacy `pulumi import` command is also supported: ```sh $ pulumi import aws:lambda/functionRecursionConfig:FunctionRecursionConfig example recursive_processor ```
