It supports data structures such as strings, hashes, lists, sets, stored sets with range queries, etc. Let's understand the flow of Redis cache in a web application: Users request a page from the web application. Web application queries the Redis store, if the data exists, then fetches the data and returns the response directly to the user. If no data is in the Redis store, the application queries the database and fetches the data, next save the same data into the Redis store so that subsequent user request can consume the data from the Redis store directly, finally returns the response to the users.
