At some point, every backend engineer hits this wall. The data keeps growing. Memory starts climbing. And suddenly, a simple read job becomes a production problem. Naveen, one of our engineers who enjoys digging into these edge cases, ran into this exact issue with DynamoDB. Instead of accepting batch reads and workarounds, he went looking for a cleaner way. This write-up walks through how to stream DynamoDB data safely using Scanamo, Cats Effect, and FS2, without loading everything into memory and without losing control of the flow. It’s practical, and written from real experience, not theory. If you’ve ever worried about memory pressure, large tables, or streaming data the right way, this one’s worth your time.
