Okay, neat! Had a chance to skim. It's really cool that you have the Cloud Formation code up and accessible (as well as the Glue script). But, is the lamdba accessible from anywhere? (or did I just miss the link?) We used Terraform instead of CloudFormation, although there are a few places it didn't/doesn't cover. We're also doing protobuf -> parquet instead of JSON; Scala instead of Python, and one of our major feature/issues is that the incoming data is out-of-order; Firehose outputs to partitions based on when the event arrived, and we're repartitioning based on when the event occurred (according to a timestamp in the message) I see you ran into the capitalization issue too :) I ran across docs somewhere that said something along the lines of Glue downcasing column names, which definitely fits observed behavior. I'm hoping to turn what we've done into a similar post, although I think it'll be a month or two before I can get to that. Edit: Oh, I also got a lot of mileage out of the Zeppelin Notebooks. Way better than a raw dev endpoint, but watch out on the cost for both :) The notebooks can be provisioned with almost a single click from the Dev endpoint console, but they changed the recipe halfway through my work on it, and now you have to also SSH into the box and run a script to setup some of the security. :/ Still totally worth it, tho.
