Your company is designing an application that will write a high volume of JSON data and will have an application-defined schema. Which type of data store should you use?
Answer options:
A. columnar
B. key/value
C. document
D. graph
Answer correct:
B
A key/value store associates each data value with a unique key. An application can store arbitrary data as a set of values. Any schema information must be provided by the application. The key/value store simply retrieves or stores the value by key. Reference: https://docs.microsoft.com/en-us/azure/architecture/guide/technology-choices/data-store-overview
