Will cuid length always be 25? #51

Closed asafyish closed 8 years ago

Hi,

Is cuid will always return a length 25 string ? Need to know for setting VARCHAR length. Couldn't find an exact answer about it.

Thanks !

Hi,

I'm not sure of the answer off the time of my head, but it shouldn't be possible for the length to vary more than 4 chars.

Hi, does it mean it will vary in [21, 25], [23, 27], [25, 29] or [21, 29] ?

Declared fixed length of cuid (eg 32 characters) will be greatly improve database performance, because storing and operating with cells, having fixed length (eg Char(32)), in database files, is much easier and quicker, than variable (VarChar(32)).

This standard is a decade old. We probably shouldn't go making changes that could break people's apps unless we have a really compelling reason to.
