Going beyond the real-time cache with Redis Stack

With the addition of new capabilities, Redis Stack pushes Redis forward and meets the expectations of software architects and developers who are having to deal with myriad new requirements. However, it also pushes the old traditional ones to the next step, which means finding new ways to resolve traditional problems with real-time performance, scalability, and high availability easily and inexpensively. Since its inception, Redis’ objective has been to provide suitable data structures and algorithms to ensure speed and minimal footprint. As an example, think of the Bitmap data structure, which grants access down to the bit level. With such flexibility, we can flag the days in a given month when a user has authenticated to a certain service:

127.0.0.1:6379> SETBIT user:032023 0 1
(integer) 0
127.0.0.1:6379> SETBIT user:032023 5 1
(integer) 0
127.0.0.1:6379> SETBIT user:032023 10 1
(integer) 0
127.0.0.1:6379> SETBIT...
