How many transactions am I going to post today? How many on Monday. What about Tuesday after a three day weekend? What about Tuesday on a 3 day weekend 4 years from now?
Each "transactions" is 100 bytes. We save the transactions for a year. We are a brand new bank that has not yet processed any transactions. How many megabytes should I define my transaction file? No, I'm not expecting a real answer to that question. Just trying to point out why it's hard, to say the least, to know how to size files of this type.
