#18669 new Bug

QuerySet.bulk_create should batch if no AutoField

Reported by: jdunck Owned by: jdunck
Component: Database layer (models, ORM) Version: 1.4
Severity: Normal Keywords: QuerySet.bulk_create
Cc: Triage Stage: Accepted
Has patch: no Needs documentation: no
Needs tests: no Patch needs improvement: no
Easy pickings: no UI/UX: no


.bulk_create branches on can_combine_inserts_with_and_without_auto_increment_pk *and* _meta.has_auto_field, but it should be
can_combine_inserts_with_and_without_auto_increment_pk or not _meta.has_auto_field.

This buglet means that even if the model doesn't have an autofield, the list will be partitioned into models with and without the PK, resulting in unnecessary query executions.

I'm assigning myself as owner because I intend to patch it.
