Description (last modified by )
At this line: https://github.com/django/django/blob/stable/2.2.x/django/db/models/query.py#L1197
batch_size param overrides compatible batch size calculation. This looks like a bug as bulk_update properly picks the minimum of two:
https://github.com/django/django/blob/stable/2.2.x/django/db/models/query.py#L504
I suggest using similar
batch_size = min(batch_size, max_batch_size) if batch_size else max_batch_size
logic in bulk_create as well. I am happy to open a PR for it.

Hi!
I added a couple of tests to the patch. Since this is the first time I'm contributing to django, I'd love to hear any feedback or advice.
Thanks.

I guess testing it will be harder than the fix!
