where the default is such that at most 999 variables per query are used.
On databases that support it (all except PostgreSQL < 9.5 and Oracle), setting
the ``ignore_conflicts`` parameter to ``True`` tells the database to ignore
failure to insert any rows that fail constraints such as duplicate unique
values. Enabling this parameter disables setting the primary key on each model
instance (if the database normally supports it).
