Should I use high numbers for user IDs in database?
Are there any benefits with starting user_id from 1000 (from <9000 users project) or 10000 for more…?

Should I use high numbers for user IDs in database?
Are there any benefits with starting user_id from 1000 (from <9000 users project) or 10000 for more…?
The advantage of starting user IDs from 1000 (even when you will have fewer than 9,000 IDs) is that they will all have the same number of digits, so that files, for example, suffixed with the UID will sort in numeric order automatically, even if the sorter only uses alphabetic numbering. And you don’t have to pad the numbers with leading zeroes to get there.
The converse is that if you only have 1000 users, numbers starting at 1,000,000,000 would look a little silly: 1,000,000,001 then 1,000,000,002 and so on.
For many purposes, therefore, it doesn’t matter which you do. A uniform number of digits has some advantages, and that is why a value other than zero or one is often used as the starting point.
