Enum extensions.filters.http.aws_lambda.v3.Config.InvocationMode

[extensions.filters.http.aws_lambda.v3.Config.InvocationMode proto]


(DEFAULT) ⁣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.


⁣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.


[extensions.filters.http.aws_lambda.v3.PerRouteConfig proto]

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.
