After Redis announced a licensing change earlier this year, multiple projects have sprung up to develop open-source code under the BSD license. In the past month, the Valkey project by Linux Foundation released version 8.0, while the original Redis project is also preparing to release version 8.0.
A key point of divergence is that the two software versions are significantly different. Redis 8.0 showcases new capabilities such as JSON support, time series data, and new search methods like vector search, which were previously separate modules.
On the other hand, Valkey 8.0 focuses on improving performance. The server may now support up to 230% more queries, with reduced latency to just 0.5ms. Memory usage has also decreased by up to 20.3%.
This direction could lead to further divergence between the two projects in the future. Another project that spun off from Redis, Redict, has not seen major updates yet.
TLDR: Redis and Valkey have diverged significantly, with Redis 8.0 introducing new features and Valkey 8.0 focusing on performance improvements. Another project, Redict, has not been updated extensively.
