Azure Cosmos DB uses the concept of Request Units per second (RU/s) to manage the performance and cost of databases. If you underprovision (by specifying too few RU/s), Cosmos DB will start throttling performance. What effect will this have on requests to access the database? The requests will be aborted immediately. Requests will be asked to retry later. Your database will halt for a period of time.
Requests will be asked to retry later.
Using the SQL API in Azure Cosmos DB you can use aggregate functions to summarize data in SELECT queries. What does the Count(p) function do? Select all options that apply.
