"""
class BulkyModel(models.Model, ModelBulkProcessMixin):
id = models.BigAutoField(primary_key=True)
name = models.CharField(max_length=10, null=False)
With ModelBulkProcessMixin , We could minimize memory usage.
Without ModelBulkProcessMixin, We shold maintain bulk array size
up to 100_000
or manually maintain arraysize up to batch_size like 10_000
if len(chunked_list)>10_000:
Model.objects.bulk_create(chunked_list)
and check remain in list again at the end.
if len(chunked_list)>0:
Model.objects.bulk_create(chunked_list)
"""
names = [f"name-{num}" for num in range(100_000)]
with BulkyModel.gen_bulk_create(batch_size=10_000) as bulk:
for name in names:
bulk.add(BulkyModel(name=name))
self.assertEqual(100_000, BulkyModel.objects.all().count())
