I think it was quite clear anyway that your client app does not know any
specific keys, and you don't have to pass an existing key as the start / end
key.

You can pass start and end keys as empty values with setRowCount() left to
default of 100 or another specific value that u want. After that first
batch, you have to pick-up the last key of the batch and make that as the
start key of the next batch query, and keep moving along like that (as
described previously in this thread)
