What framework are you using to connect to the datastore? I've not used JDO or JPA, but in Objectify you can set an offset and a limit on a query. In onRangeChanged you can get them like this: Range range = display.getVisibleRange(); Integer offset = range.getStart(); Integer limit = range.getLength();
So there's no need to work with cursors. If this functionality is not exposed through your datastore layer you could always use the low level api.
