Prerequisites

Before we attempt to design our schema for DynamoDB, we must first gather some prerequisite data on the use case the schema needs to support. Unlike relational databases, DynamoDB is sharded by default, meaning that the data will live on multiple servers behind the scenes so designing for data locality is important. We'll need to put together the following list for each schema design:

  • List of entities (ER Diagram)

  • Estimated volumes and throughput for each entity

  • Access patterns that need to be supported (queries and writes)

  • Data retention requirements
