Chunk large querysetsinto small chunks, and iterate over them without killing your RAM.
Project description
Chunk large querysetsinto small chunks, and iterate over them without killing your RAM.
Usage:
from chunkator import chunkator
for item in chunkator(LargeModel.objects.all(), 200):
do_something(item)
This tool is intended to work on Django querysets. Your model must define a pk field (this is done by default, but sometimes it can be overridden) and this pk has to be unique. django-chunkator has been tested with Postgresql and SQLite, using regular PKs and UUIDs as primary keys.
You can also use values():
from chunkator import chunkator
for item in chunkator(LargeModel.objects.values('pk', 'name'), 200):
do_something(item)
