Sets your function's recursive loop detection configuration.

When you configure a Lambda function to output to the same service or resource that invokes the function, it's possible to create an infinite recursive loop. For example, a Lambda function might write a message to an Amazon Simple Queue Service (Amazon SQS) queue, which then invokes the same function. This invocation causes the function to write another message to the queue, which in turn invokes the function again.

Lambda can detect certain types of recursive loops shortly after they occur. When Lambda detects a recursive loop and your function's recursive loop detection configuration is set to Terminate, it stops your function being invoked and notifies you.

Note:

This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginPutFunctionRecursionConfig and EndPutFunctionRecursionConfig.

Namespace: Amazon.Lambda

Parameters

request
Type: Amazon.Lambda.Model.PutFunctionRecursionConfigRequest

Container for the necessary parameters to execute the PutFunctionRecursionConfig service method.

cancellationToken
