Sboire,
  There is an "offset" parm on the fetch, so yes, you can get 1000
records at a time in a loop.
I believe however this is discouraged because it will eat up your CPU
quota, and potentially you could hit other limits and quotas.  Imagine
if you had 5 million records.  Reading 1000 at a time would take 5000
calls.  Even on a MySQL database with PHP for example, you would
probably hit the various CPU limits per task reading so many records
in one round-trip from the client to the server.
