The Redis In-memory Data Store Literacy (Beginner Level) benchmark measures your knowledge of Redis features and using the CLI to interact with the Redis data store. You will be evaluated on your understanding of the benefits and limitations of HyperLogLog structures and how to use them in Redis and your ability to work with lists, hashes, and sets. Learners who score high on this benchmark demonstrate that they have the skills to work with the different data structures available in Redis.

Topics covered

  • describe the properties of sorted sets and illustrate how they contrast with regular Redis sets
  • describe the use cases of the Redis data store
  • distinguish between list and set data structures and apply the Redis CLI commands that apply to sets
  • extract elements from Redis lists individually or in bulk
  • identify the types of data that can be stored in Redis and the properties of the different data structures
  • illustrate the use and limitations of the HyperLogLog structures when it comes to tracking unique values
  • invoke create, read, update and delete operations from the Redis CLI
  • perform set operations such as union, intersection, and set difference on Redis sets
  • perform string operations on Redis data
  • recognize how Redis supports connections via various clients
  • recognize the features of list structures in Redis and illustrate the types of operations that can be performed with them
  • use the Redis hash structure to store and extract data in the form of a map
