"""The configuration parameters used while performing a rolling upgrade.
:param max_batch_instance_percent: The maximum percent of total virtual
machine instances that will be upgraded simultaneously by the rolling
upgrade in one batch. As this is a maximum, unhealthy instances in
previous or future batches can cause the percentage of instances in a
batch to decrease to ensure higher reliability. The default value for this
parameter is 20%.
:type max_batch_instance_percent: int
:param max_unhealthy_instance_percent: The maximum percentage of the total
virtual machine instances in the scale set that can be simultaneously
unhealthy, either as a result of being upgraded, or by being found in an
unhealthy state by the virtual machine health checks before the rolling
upgrade aborts. This constraint will be checked prior to starting any
batch. The default value for this parameter is 20%.
:type max_unhealthy_instance_percent: int
:param max_unhealthy_upgraded_instance_percent: The maximum percentage of
upgraded virtual machine instances that can be found to be in an unhealthy
state. This check will happen after each batch is upgraded. If this
percentage is ever exceeded, the rolling update aborts. The default value
for this parameter is 20%.
:type max_unhealthy_upgraded_instance_percent: int
:param pause_time_between_batches: The wait time between completing the
update for all virtual machines in one batch and starting the next batch.
The time duration should be specified in ISO 8601 format. The default
value is 0 seconds (PT0S).
