Node + AWS for data ingress has been pretty painful in my experience (mostly dynamo feeds from large csv (whois database)). In the end, rewrote in C# (core 2) and it was able to complete more reliably. I'm guessing that go and rust would also be better. I like node, really like JS, but I just think that maybe the AWS libraries aren't that great in the space. It would run for 3-5 hours, then just blow up unexpectedly, even with plenty of memory overhead, and not really bandwidth limited, with appropriate retries and slowdown for dynamo rejections. If I never have to write ETL pipelines again, I won't be upset about it.
