A Cosmos DB container has a 500 RU read cost for a specific document. Which action would most reduce the RU consumption for future reads?
- A Use strong consistency
- B Reduce document size by removing unused properties (correct answer)
- C Increase provisioned throughput
- D Add more regions
Shortcut: Read cost scales with document size. Removing unused properties or using projections to retrieve partial documents reduces data transferred and lowers RU consumption per read.
