BatchProcessor: pattern/best practices for passing additional parameters from lambda_handler() to record_handler()?

[cmurtaugh]

Hi --

I'm following the documentation for batch-processing SQS messages, and it works well. I'd like to know if there are any examples / best practices for how to pass additional information from the lambda_handler to the record_handler. For example, I want to retrieve some SSM parameters in the lambda_handler code and make them available to the record_handler code. Is there a good way to do this?

Thanks!
