MapLambda function is already connected for you, so let us quickly check if it works as expected!
MapLambda has a correctly configured trigger to receive messages from the
MapLambdafunction to view its configuration.
MapLambdafunction has a DynamoDB trigger and this trigger points to the
StateTable(see figure below).
Any row written to the
StateTable should trigger the
MapLambda function. Therefore, you should be able to see logs for the Lambda invocations.
Alternatively, you can observe the outputs of the
MapLambda function in the DynamoDB
ReduceTable. To do that, navigate to the DynamoDB service in the AWS console, click
Items on the left, and select
ReduceTable. At this stage you should see multiple rows similar to the image below.
