Redis: Open-Source In-Memory Data Store
Open-source in-memory data structure store used as a database, cache and message broker with support for various data structures.
What is Redis?
Redis is an open source, in-memory data structure store that can be used as a database, cache, and message broker. It provides high availability, performance, replication and supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs and geospatial indexes and streams.
Some key features of Redis:
- Supports data structures like strings, hashes, lists, sets, sorted sets, bitmaps, hyperloglogs, geospatial indexes and streams
- Open source, in-memory and stores data in RAM for high performance and low latency
- Master-slave asynchronous replication for high availability
- Runs completely in memory but supports durability using snapshotting and append-only files
- Multi-model database able to handle different kinds of workloads
- Single-threaded avoids overhead from context switching, ideal for CPU-bound workloads
- Used as database, cache, message broker, queuing system, gaming leaderboards, real-time analytics, geospatial, session store etc.
Redis powers many high-traffic sites and applications by providing a flexible data model, replication for scaling reads and high performance. Its versatility has made it a popular choice as a database, cache and message broker in modern applications.
