[$] The race to replace Redis

On March 21, Redis Ltd. announced that the Redis "in-memory data store" project would now bereleased under non-free, source-available licenses, starting with Redis7.4. Thenews is unwelcome, but not entirely unexpected. What is unusual with this situation isthe number of Redis alternatives to choose from; there are at leastfour options to choose as a replacement for those who wish to staywith free software, including a pre-existing fork called KeyDB and the Linux Foundation's newly-announced Valkey project. The question now is which one(s)Linux distributions, users, and providers will choose to take its place.
