Hi

I generate ids by default setting got the length is 19, how can i reduce the length down to 15?

this gives you 64 bit number, There is no way you can short this, unless you write your own.

if you convert it to base62 you ll have a shorter id for sure

There are several methods in this package you can use to reduce the number of characters an ID uses. Like the Base58 method here, https://github.com/bwmarrin/snowflake/blob/master/snowflake.go#L250.
