Redis changed its license because they don’t want people making money off them. Open edX uses Redis. What are the affects going to be?
Most likely many will switch to Valkey because AWS will switch to that; and if not Valkey, there are several other options that are 100% compatible with Redis as far as we use it for Open edX. What’s more, the things we use Redis for (caching, message queue, etc.) aren’t really tied to Redis [variants] and could be swapped out for other backends if necessary. So I don’t expect much impact.
There shouldn’t be much direct effect, as Open edX does not offer Redis itself as a service; rather, it uses Redis in providing an unrelated service. Anyone running a standard Redis cluster wouldn’t invoke the more interesting parts of the SSPL.
