Redis

When designing a caching solution in Redis for a one-to-many relationship, such as a quiz with multiple member answers, it’s important to choose the right data structures to ensure efficient storage and retrieval. Redis offers several data structures that can be used to achieve this, including hashes and sets. Below, we discuss two common approaches: using hashes and using sets combined with hashes.
