+
+This module allows to seemlessly split a big job into smaller jobs.
+
+It uses ``queue_job_batch`` to group the created jobs into a batch. 
+
+Example:
+
+.. code-block:: python
+
+  class ResPartner(models.Model):
+      # ...
+
+      def copy_all_partners(self):
+          # Duplicate all partners in batches of 30:
+          self.with_delay(batch_size=30).copy()
+
+  # ...
+  self.env['res.partner'].search([], limit=1000).copy_all_partners()
+
+This will create 34 jobs, each one copying 30 partners (except the last one which will copy 10) and will group them into a batch.
+
+Instead of ``batch_size``, one can also use ``batch_count`` to specify the number of batches to create instead.
