Description

Documentation

data ShrinkPolicy Source #

Policy for customizing shrink operations. Allows configuration of decommissioning timeout and targeted instance shrinking.

See: newShrinkPolicy smart constructor.

Constructors

ShrinkPolicy'
Fields decommissionTimeout :: Maybe Int The desired timeout for decommissioning an instance. Overrides the default YARN decommissioning timeout. instanceResizePolicy :: Maybe InstanceResizePolicy Custom policy for requesting termination protection or termination of specific instances when shrinking an instance group.

newShrinkPolicy :: ShrinkPolicy Source #

Create a value of ShrinkPolicy with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:decommissionTimeout:ShrinkPolicy', shrinkPolicy_decommissionTimeout - The desired timeout for decommissioning an instance. Overrides the default YARN decommissioning timeout.

$sel:instanceResizePolicy:ShrinkPolicy', shrinkPolicy_instanceResizePolicy - Custom policy for requesting termination protection or termination of specific instances when shrinking an instance group.

shrinkPolicy_decommissionTimeout :: Lens' ShrinkPolicy (Maybe Int) Source #

The desired timeout for decommissioning an instance. Overrides the default YARN decommissioning timeout.

shrinkPolicy_instanceResizePolicy :: Lens' ShrinkPolicy (Maybe InstanceResizePolicy) Source #

Custom policy for requesting termination protection or termination of specific instances when shrinking an instance group.
