Now, i want to users id start from 1000 and increase by one.

Answer 1

You can have a key called user:id, which will be a number that you will increment to obtain new ids. In your case, you can set the initial value to 1000:

SET user:id 1000

Then by using INCR you will be able to get a new id for your next user:

INCR user:id

Depending on the language you use, there may be already some tools to solve this problem. I would recommend you check Ohm, or one of the ports.
