Episode 6 — Match Real Tools to Use Cases: Cassandra, MongoDB, Neo4j, DynamoDB, Cosmos
This episode helps you connect well-known platforms to the workload patterns they are commonly chosen for, which is exactly how product references tend to appear in DS0-001 questions. You’ll learn how Cassandra-style wide-column systems align with high-throughput distributed writes and predictable query paths, how MongoDB aligns with document-centric applications that need schema flexibility and developer-friendly JSON-like structures, and how Neo4j aligns with relationship traversal problems where the links are as important as the nodes. We’ll also cover what it means when a prompt mentions managed services like DynamoDB or Cosmos, including operational implications such as capacity modes, regional replication, availability features, and shared responsibility boundaries. The goal is not memorizing marketing claims, but being able to infer the “why” behind a tool choice, spot when a tool is being used outside its sweet spot, and recommend practical fixes like key redesign, indexing changes, or a more appropriate storage model.
