It will only pull unnecessary data when you use offset parameter in
fetch(limit,offset=0). Because when you set an offset, the datastore
still need to iterate all previous data before that offset.

Sorry if it was unclear. This would only pull Thing 6.

when you say the same is not true of filter, are you saying that
Thing.all().filter('value >' 5).get()
will pull Things 1,2,3,4,5(like the offset issue) the records from the
datastore, but just return Things 6 from the query.
this seems wrong to me.
The reason im making sure on this is that
Hi,
The same is not true of filter(). Filter will start at the first value
larger than x, and should be used if you want to paginate your records.
Brett Slatkin's IO talk covers scalable pagination recipes, and I suggest
checking it out:

ok, i wanted to be sure about this, as pulling all the records and
just returning one would have been a performance disaster for my app.
my question was raised because i was a little surprised to read that
offset queries still pull all the 'upto' offset out of the store.
does the same apply to T
Only '1'
