Is Redis really fast?

Why is Redis so fast?

Built for Speed & Languages To work as quickly as it does, Redis uses a dataset that is in-memory. In order to maintain the data, you can save it to disk occasionally or attach all commands to a log. In fact, you don't always want persistence, so you can turn it off if you're using it to temporarily cache.

Is there anything faster than Redis?

Redis vs MongoDB Speed This means that as the data stored in the database gets larger and larger, MongoDB is able to operate much faster than Redis. Redis is only significantly faster when the stored data is relatively small in size.

How fast is Redis get?

Because memory access is faster than disk access (0.1 μs vs. 10 ms), Redis performs extremely well when compared to disk-‐centric databases. On top of the high performance, Redis gives you two options to persist its data durably: (1) using snapshots and/or (2) using an append-‐only file.

Is Redis cache fast?

Redis is extremely fast. It delivers sub-millisecond response times that enable millions of requests per second to power demanding real-time applications. Typically, you'll want to store frequently accessed data in Redis so that whenever the data is requested, it can come from the cache instead of your database.
