I believe the sequences track the current value of the sequence.
When your client requests 100 values, it would use 1-100, but Phoenix only needs to know that the next value it can give out is 101. I'm not 100% sure, but I think this is how it works.
What are you concerned about? Cheyenne Forbes wrote:
I am not sure how sequences work in phoenix but something popped up in my mind. If I request 100 values from a sequence will there be 100 values stored in the database or just 1 value which is "100" telling phoenix the is the number to be incremented?
