AWS Lambda filter config

Used in: PerRouteConfig

• string arn = 1

  The ARN of the AWS Lambda to invoke when the filter is engaged Must be in the following format: arn:<partition>:lambda:<region>:<account-number>:function:<function-name>

• bool payload_passthrough = 2

  Whether to transform the request (headers and body) to a JSON payload or pass it as is.

• Config.InvocationMode invocation_mode = 3

  Determines the way to invoke the Lambda function.

Used in: Config

• SYNCHRONOUS = 0

  This is the more common mode of invocation, in which Lambda responds after it has completed the function. In this mode the output of the Lambda function becomes the response of the HTTP request.

• ASYNCHRONOUS = 1

  In this mode Lambda responds immediately but continues to process the function asynchronously. This mode can be used to signal events for example. In this mode, Lambda responds with an acknowledgment that it received the call which is translated to an HTTP 200 OK by the filter.

Per-route configuration for AWS Lambda. This can be useful when invoking a different Lambda function or a different version of the same Lambda depending on the route.

• optional Config invoke_config = 1
