<p>
Batch size for rollback to the old endpoint fleet. Each rolling step to provision capacity and turn on traffic on
the old endpoint fleet, and terminate capacity on the new endpoint fleet. If this field is absent, the default
value will be set to 100% of total capacity which means to bring up the whole capacity of the old fleet at once
during rollback.
