lambda

Invokes an AWS lambda for each message. The contents of the message is the payload of the request, and the result of the invocation will become the new contents of the message.

lambda:
parallel: false
function: ""
region: eu-west-1

It is possible to perform requests per message of a batch in parallel by setting the parallel flag to true. The rate_limit field can be used to specify a rate limit resource to cap the rate of requests across parallel components service wide.

In order to map or encode the payload to a specific request body, and map the response back into the original payload instead of replacing it entirely, you can use the process_map or process_field processors.

Error Handling

When all retry attempts for a message are exhausted the processor cancels the attempt. These failed messages will continue through the pipeline unchanged, but can be dropped or placed in a dead letter queue according to your config, you can read about these patterns here.

Credentials

By default Benthos will use a shared credentials file when connecting to AWS services. It's also possible to set them explicitly at the component level, allowing you to transfer data across accounts. You can find out more in this document.
