Redis Cli Scan Example . These are recorded in microseconds. Redis sscan command iterates the elements of a set stored at a specified key. 【Redis运维】使用scan遍历所有key运维易 from www.linuxe.cn In this case, we are using the sample datasets provided in the previous sections. The initial cursor value is 0, and when scan returns 0 as the next cursor value. In order to fetch the user with a specific email address you just need to do a get operation on the key with the email prefix and then another one on the key with the user prefix.
