UUID stands for something
UNIQUE. How that happened that it simply
doesn’t work? Or even worse: it doesn’t work sometimes.
I had to use a program which generates some random data in the database. The primary key is
UUID, so the program generates a lot of UUIDs. It uses the standard Java’s way of generating UUIDs, the function:
That program failed twice, it was a database error. The error was that the UUID exists in the database. I’ve created only a litttle bit over 50k of database rows. There were two collisions.
I told that the author of the software, he said that he had the same situation last week.
It looks like I was really lucky to get the same UUID randomly generated twice :)
