How to generate unique guids in snaplogic

[yash_verma]

Hi
I am using math.random() function of mapper component to generate unique guids. I am worried that after repetitive use of this function it will generate duplicate results. Is there any way i can be sure that it doesnt generate same guids. Is there any other efficient way of doing this. Please let me know.

Thanks

Yash

No. I’d just use a randomUUID. You’re extremely unlikely to get repeats. We use them all the time when we need unique values and I’m not aware of any issues related to repeats.

Actually, how about this?

(Date.now().getTime() + Math.randomUUID()).substr(0,36)

That will give you a value like 16008933027615cf16319-1480-4260-9c84. The time component changes every millisecond, plus a random component, and it’s the length you want.
