Summary: In-memory caching layer (via dedicated gateway) reducing RU cost/latency for repeated reads.

Answer Key

Answers are listed at the very end so you can attempt the questions first.

  • Q1 (Integrated Cache): A. Reduced RU consumption and latency for repeated point reads and queries — The integrated cache reduces RU cost and latency by serving repeated reads/queries from an in-memory cache.
  • Q2 (Integrated Cache): A. A dedicated gateway — The integrated cache is provisioned through a dedicated gateway deployment.
