The "schema-less" promise of NoSQL is often a trap. In reality, the lack of a rigid schema makes your data design more critical, not less. A poor model in a distributed system doesn't just slow down queries—it breaks scalability and inflates your cloud bill.
In this session, we strip away the "just dump it in JSON" myth and focus on the deliberate architectural decisions required for production-grade systems. We will walk through the lifecycle of a NoSQL model, from JSON specifications to advanced partitioning strategies. You will learn how to handle the nuance of NULL vs. undefined values and, crucially, how to select a Partition Key that prevents "hot partitions." We’ll conclude by exploring how Materialized Views can solve the puzzle of cross-partition queries without sacrificing speed.
