I'm creating short links such as

https://example.page.link/4Xyz

using Firebase short links API

The unique part of a link has 4 chars (upperCase letters, lowerCase and numbers allowed). As far as i understand it gives us only ~ 500k unique combinations. What will be if i over exceed this amount?

CodePudding user response：

The short unique codes are generated as needed, and can be longer than 4 characters.

There is no documented limit to the number of dynamic links you can generate. There may be a physical limit, but there's nothing in the code limiting it.
