Hi!
I have recently uploaded a new code snippet to my site. FetchSpecBatchIterator allows for iterating over a large query result without having all matching objects in memory at the same time.
The FetchSpecBatchIterator works by fetching primary keys only shortly before delivering the first batch of objects. Batches are then created from subsets of the retrieved set of primary keys. Though retrieved objects may represent fresher data than was available at the time of the first fetch, their selection however will not be modified by changes to the database occurring after the initial fetch.
