Hi there, when i was looking for a good explanation of what is and how to use the gen stage, i found a great conf vid by @josevalim, here → https://www.youtube.com/watch?v=XPlXNUXmcgE, watch it too, he covered all the question i had.

Thank you!

It took a long time for GenStage to click for me.
It wasn’t obvious that producers emit events from any
handle_*callback by populating a list in the second element of the return tuple.The HexDocs are quite good, particularly once the section on buffering demand made sense it all came together.

This blog post covers polling SQS from a GenStage producer, there’s a GitHub repo linked with some sample code.
I’d also consider using ConsumerSupervisor to handle each SQS message in a new process.
