Major Description
It is becoming more and more common to use UUIDs.
For example as a primary key for security reasons (non-predictable ids). Some databases are implementing them natively.
I think it is very interesting that Phoenix also has this type of data that is more and more used.
I have already implemented the functionality and I will add the branch with the changes that I have seen necessary. The tests have passed satisfactorily, but there are some internal technical issues (not functional) that I need to discuss and I will expose them in github (I think it is more correct to do it there than in the jira).
