What is Redis and why use it?

Redis offers purpose-built in-memory data structures and operators to manage real-time geospatial data at scale and speed. Commands such as GEOADD, GEODIST, GEORADIUS, and GEORADIUSBYMEMBER to store, process, and analyze geospatial data in real-time make geospatial easy and fast with Redis.

Is Redis good for session?

Redis is perfect for storing sessions. All operations are performed in memory, and so reads and writes will be fast. If you cannot afford losing any sessions, set appendfsync always in your configuration file. With this, Redis guarantees that any write operations are saved to the disk.

When was the first version of Redis released?

Since its initial release in 2009, open-source Redis has evolved beyond a caching technology to an easy to use, fast, in-memory data store, which provides versatile data structures and sub-millisecond responses. Redis reached a major milestone with the release of 5.0, which includes a variety of advancements and improvements.
