Modern NoSQL databases

What is Redis?

The open source, in-memory Redis (for REmote DIctionary Server) key/value store is generally used as an application cache or quick-response database. Redis offers unsurpassed speed, dependability, and performance since it saves data in memory instead of on a disk or solid-state drive (SSD).


Salvatore Sanfilippo, the first Redis developer, sought to increase the flexibility of his Italian firm. So naturally, therefore, he launched the project. From there, he created Redis, which today has a variety of applications like a database, cache, and queue.

Redis has response rates that are less than one millisecond, enabling millions of queries per second for real-time applications in sectors. Redis has been rated the "Most Loved" database by Stack Overflow, which currently makes it one of the most well-liked open-source engines.



Given that all Redis data is in memory, retrieving it quickly and efficiently is possible, resulting in lightning-fast performance for both read and write operations.


Redis allows writing typically complex code in smaller, more concise chunks.

Replication and Persistence

Data can be duplicated to many replica servers using Redis' asynchronous, synchronous replication feature and primary-replica architecture.


Redis provides a single node main or clustered topology for its primary-replica architecture. This enables you to develop extremely reliable systems with stable performance.

Open Source

A thriving community backs open source project Redis. Redis is based on open standards and has a wide variety of clients. Therefore, there is no vendor or technology lock-in.

Flexible Data Structures

Redis provides a wide range of data structures to satisfy your application demands, unlike other key-value data stores offering only a small selection.

Redis Queues

Redis can queue jobs that otherwise may take web clients longer than normal to complete.

Redis Components

Redis Sentinel:Redis Sentinel is an independent distributed solution that aids developers in tuning their instances for maximum client availability.
Redis Cluster:Redis Cluster is a distributed version of Redis that distributes datasets among several nodes automatically.
Redis Pub/Sub:Redis enables customers to develop high-performance chat and messaging applications for every one of their apps and services using publish and subscribe or (Pub/Sub) commands.

Use Cases

Real-time analytics - Redis is perfect for real-time analytics, online marketing initiatives, and AI-driven machine-learning procedures since it can deal with data with a latency of less than one millisecond.
Location-based applications - Redis has geographic indexing, sets, and operations, making creating location-based apps and services easier.
Caching for databases - With its in-memory data storage capabilities, Redis can enable extremely responsive database designs and manage enormous volumes of real-time data.
Gaming leaderboards - When creating real-time leaderboards, game developers frequently choose Redis.
Rich media streaming - Redis provides quick in-memory data storage for use cases, including live streaming. For example, for CDNs to broadcast films to countless mobile and desktop users simultaneously, Redis can store metadata regarding user profiles, viewing histories, and manifest files.

Frequently Asked Questions

Which company uses the Redis database?

Countless companies leverage Redis in their tech stacks, including Uber, Airbnb, Pinterest, Shopify, Twitter, and GitHub.

Why is Redis so Popular?

Because Redis is an in-memory database, it is quick. In comparison to random disk I/O, memory access is several times quicker. Redis is also one of the few databases that can accommodate millions of operations per second.

What language is Redis developed in?

Redis is built in ANSI C and doesn't require additional dependencies to run on most POSIX platforms, including Linux, BSD, and Mac OS X. The two operating platforms where Redis is being created and evaluated the most are Linux and OS X.
