But one can say for example that an upper limit of 50000 (just a sample)
page fetches could be the upper limit.
My second question, now I know what fetches are, is:
1.) The partial result set will be returned to the user ?
2.) If the answer for the question 1 = true then a flag wll be returned
indicating that this is a partial result set ?
3.) If the answer for the question 2 = true the user could ask to
process N more fetches ?
Or the user will get just a time-out error ?
Sorry for the lame questions people, I just want to understand it a bit
more.
see you !
