def queryset_iterator(queryset, chunksize=1000): | |
''''' | |
Iterate over a Django Queryset ordered by the primary key | |
This method loads a maximum of chunksize (default: 1000) rows in it's | |
memory at the same time while django normally would load all rows in it's | |
memory. Using the iterator() method only causes it to not preload all the | |
classes. |
