Overview/Description

Redis offers a variety of data structures and collections which enable developers to deliver several types of high-performing applications to end-users. In this course, you'll learn how to work with Redis's different data structures, namely lists, hashes, and sets. You'll then learn to perform various set operations, such as union, intersection, and set difference. Next, you'll distinguish sorted sets from regular sets and learn how to work with them. You'll then examine the benefits and limitations of HyperLogLog structures and how to use these in Redis. Upon completing this course, you'll be able to compare and work with each of these structures and recognize their use cases.
