为什么每次incr都要调用 expire

else
-- 没有达到阈值 value + 1
redis.call("INCRBY", key, 1)
redis.call("EXPIRE", key, 2)
return curentLimit + 1
end

The issue only identifies an else branch containing Redis INCRBY and EXPIRE calls; no source file or test is named. Start by locating this Lua script in the repository and checking the Redis command semantics and surrounding threshold logic. Done means documenting whether the expiration call is intentional and identifying the required behavior if it is not.
