Redis is an open source, in-memory data structure store, used as a database, cache and message broker. It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes with radius queries and streams. Redis has built-in replication, Lua scripting, LRU eviction, transactions and different levels of on-disk persistence, and provides high availability via Redis Sentinel and automatic partitioning with Redis Cluster.
Is Redis a cache or database?
Redis is an open source, in-memory data store that can be used as both a cache and a database. It is often used as a cache in front of a database because it is very fast. Redis is also used as a database because it supports a rich set of data types and has good support for atomic operations.
Is Redis better than SQL?
Redis is an open source, in-memory data structure store that can be used as a database, cache, and message broker. It supports various data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, and geospatial indexes with radius queries.

SQL is a standard language for storing, manipulating, and retrieving data in relational databases. SQL databases are widely used for transaction processing, data warehousing, and analytics applications.
Redis is better than SQL for some use cases, but not all. For example, Redis is better for applications that require real-time data access, high throughput, or support for complex data structures. SQL is better for applications that require ACID compliance or need to run on a relational database management system (RDBMS).
Is Redis better than MongoDB?
There is no definitive answer to this question as it depends on a number of factors, such as the specific needs of your application and the trade-offs you are willing to make. However, in general, Redis may be a better choice if you need a highly scalable data store with very low latency, while MongoDB may be a better choice if you need a flexible document-oriented database. Is Redis faster than memory? Redis is an in-memory database that offers high performance and scalability. In terms of speed, Redis is often faster than memory, due to its efficient data structures and caching mechanisms. However, memory-based databases can offer better performance in some cases, depending on the data structures used and the workloads involved. Can I use Redis as a database? Yes, you can use Redis as a database. It is an open source, in-memory data structure store that can be used as a database, cache, and message broker. It supports data structures such as strings, hashes, lists, sets, and sorted sets with range queries, bitmaps, hyperloglogs, and geospatial indexes with radius queries.
