Question

A company is developing an application that performs intensive in-memory operations on advanced data structures such as sorted sets. The application requires sub-millisecond latency for reads and writes. The application occasionally must run a group of commands as an ACID- compliant operation. A database specialist is setting up the database for this application. The database specialist needs the ability to create a new database cluster from the latest backup of the production cluster. Which type of cluster should the database specialist create to meet these requirements?
