The problem/use-case that the feature addresses

local exists = redis.call('EXISTS', KEYS[1])
if exists == 1 then
    redis.call('HSET', KEYS[1], 'expire', ARGV[1])
end
return exists

A description of the problem that the feature will solve, or the use-case with which the feature will be used. I'm currently using this script via EVAL. But I think the best option would be if we have the HSETXX command.

Description of the feature HSET if keys exist and return true/false if keys exist

A description of what you want to happen. HSETXX only for existing keys and return true/false if key exist

Alternatives you've considered HSETNX, but it is only for non-existing keys

Any alternative solutions or features you've considered, including references to existing open and closed feature requests in this repository. HSETXX searching do nothing

Additional information
