Lambda function requests and Payload

[rbruhn]

Is it correct that in using LambdaClient invoke(), the whole payload is handled by a single Lambda instance? Or will it scale, dividing each record of the Payload into single lambda instance?

In my particular case, I have thousands of images to process and would like to send 100 at a time, never really overloading the number of Lambda instances created. I had planned to do this using concurrency with Guzzle Pool. However, that option doesn't seen to exist in the LambdaClient. Which, means I would need to create the signature manually.

Or, is there something I'm missing? I'd appreciate any feedback on the issue.
