Hello
GUID is a unique id assigned to evey new object in Elgg (http://docs.elgg.org/wiki/GUID). I am wondering if there is any theoretical or practical limit on the number of objects that can live in the system, before we reach the limit for GUID?
Thanks

You must log in to post replies.The theoretical limit is 2^64. That's 18 billion billion. So no, not a practical limit.
18 446 744 073 709 551 615
;-)
Enjoyy
Not really helpful for answering the question but to be more precise concerning the above answers:
18 billion billion = 18 quintillion (US and scientific notation) or trillion (in other countries).
As an exponential of 2 the number has to be divisible by 2 and therefore even:
18 446 744 073 709 551 616
;-)
Ohh lolzz
Try php code to store your ... 616 into mysql.
Then come back here to post the bounds error message
That my sql will give you......
A mathematician starts to count at 1 ... most computer systems are starting at 0. That's the difference!
So, if you want to be precise you can say that the range goes from 0 to 18 446 744 073 709 551 615, but the amount of numbers is 18 446 744 073 709 551 616.
Never mind, I know what you mean ... I was just kidding!
Sign bit in my sql for guid# ;oO
