## History

RedisShake is a project actively maintained by the [Tair team](https://github.com/tair-opensource) at Alibaba Cloud. Its
evolution can be traced back to its initial version, which was forked
from [redis-port](https://github.com/CodisLabs/redis-port).

During its evolution:

- The [RedisShake 2.x](https://github.com/tair-opensource/RedisShake/tree/v2) version brought a series of improvements
  and updates, enhancing its overall stability and performance.
- The [RedisShake 3.x](https://github.com/tair-opensource/RedisShake/tree/v3) version represented a significant
  milestone where the entire codebase was completely rewritten and optimized, leading to better efficiency and
  usability.
- The current version, [RedisShake 4.x](https://github.com/tair-opensource/RedisShake/tree/v4), has further enhanced
  features related to readers, configuration, observability, and functions.
