Jarek Jarcec Cecho commented on SQOOP-1168:
-------------------------------------------

Thank you for looking at my notes [~vybs]. After reading the latest proposal 
and the comments I have two notes:

1) I'm still not entirely sure how the framework will determine that given job 
is incremental or not? Given the fact that framework don't know anything about 
the underlaying configuration objects (and shouldn't need to know anything), 
I'm assuming that we need some explicit way to say "this is incremental append 
mode job", right?

2) I'm wondering what is our thinking of storing the "last values". Do we want 
to preserve only the "last values" from latest submission or even the history 
across multiple submissions?
