Frank, You have received several suggestions on this. Here's one more that we do with data that we get from our parent company. If you have access to somebody who can make a minor modification to the FTP send commands on the other end, you could have them simply change their FTP commands to do an append instead of a replace. Then have them just FTP the data into generation 0 of the GDG. When you run your job, just use generation 0 and as the last step of the job, create an empty +1 generation. The other benefit of this type of scenario is that if for some reason the other end neglected to send a file, you aren't re-processing yesterday's data.

A file is received (via FTP) 7 days a week from somewhere. The FTP writes to generation +1. Problem: The program that uses the file(s) runs only every business day. On a regular Tuesday-Friday it needs to only read the most recent generation (0). But on Monday it needs to read (0), (-1) and (-2). And of course there are holidays to consider. Thoughts on how this can be addressed?
