Redis [QUESTION] Does Redis have Set with condition?

I am looking for something like this:

update data
set data = new_data
where data.updated_at < new_data.updated_at

I can't find a solution for this problem, The close one is to use WATCH but unfortunately it can't watch for specific value condition.

If Redis can't do this, what is the issue here?

Usually, the easiest way to do that would be to use Lua (EVAL/EVALSHA). You can do it with WATChH, but getting it right is really really hard. With Lua: effortless
