1Data models and partition design

• 1.1Non-relational data modeling

  Understand non-relational modeling in Azure Cosmos DB for NoSQL: embedding vs referencing, denormalization, multiple entity types in one container, id/partition key/unique keys, default TTL, and versioning.

• 1.2Partition design

  Understand choosing a partition key, workload-based strategy, cross-partition query cost, evaluating data/throughput distribution, and synthetic and hierarchical partition keys.

• 1.3Sizing and scaling

  Understand evaluating throughput/storage requirements, request units (RU/s), serverless vs provisioned vs free tier, autoscale, database-level throughput, and global distribution cost.
