[tidb](https://www.tidb.io/) reports 40k GitHub stars, 6.2k forks, and 6.5k open issues, last pushed Jul 10, 2026. [redis](http://redis.io) has 75k stars, 25k forks, and 2.9k open issues, last pushed Jul 10, 2026. Figures are from public GitHub metadata via [tidb's repository](https://github.com/pingcap/tidb) and [redis's repository](https://github.com/redis/redis). | | [tidb](/tools/pingcap-tidb.md) | [redis](/tools/redis-redis.md) | | --- | --- | --- | | Tagline | Scalable, cloud-native database with ACID transactions and vector search support. | Redis is a preferred cache, data structure server, and document & vector query engine for real-time applications. | | Stars | 40,273 | 75,394 | | Forks | 6,226 | 24,718 | | Open issues | 6,475 | 2,867 | | Language | Go | C | | Adopt for | TiDB is a scalable, cloud-native database that supports both transactional and analytical processing with ACID guarantees. | Redis is an in-memory database designed as a versatile cache and data structure store with advanced features such as JSON operations and vector searches, making it suitable for real-time applications. | | Persona | - | - | | Runtime | - | - | | License | Apache-2.0 | Other | | Categories | Data & Retrieval, Vector Databases | Data & Retrieval, Vector Databases | ## Trust and health _Sourced signals - not a safety guarantee.
