1) What is a group - does it exist prior to records being inserted? How
many groups are you working with? How long do they live for?
2) #1 but for element
3) How many records per second per group per element are you anticipating?
Are their spikes?
4) How long does a group/element live for? You can put 10 record per second
over 3 years and still be under 100 million records (the size of your
seq_number)
5) How quickly do you need the seq_number - if you batch created them once
a minute would that work? Does it need to be quicker than that? Slower than
that? Or is it an immediate need?
That's a starting point.....
