Hasan Savran makes use of a cache:
We are ready to write some code now. Integrated Cache works only in Eventual Consistency for now. So, we need to send requests in Eventual consistency to test the Integrated Cache. To do that, we need to use requestOptions parameter in SDK. You can change your database consistency level to Eventual too for testing if you like. Don’t forget to change it back later!
Hopefully that limitation changes later, but in the meantime, click through to see how to use the integrated cache in Cosmos DB.
