# Cloud Dataproc API . projects . locations . autoscalingPolicies

## Instance Methods

Creates new autoscaling policy.

Deletes an autoscaling policy. It is an error to delete an autoscaling policy that is in use by one or more clusters.

Retrieves autoscaling policy.

Gets the access control policy for a resource. Returns an empty policy if the resource exists and does not have a policy set.

Lists autoscaling policies in the project.

Retrieves the next page of results.

Sets the access control policy on the specified resource. Replaces any existing policy.

Returns permissions that a caller has on the specified resource. If the resource does not exist, this will return an empty set of permissions, not a NOT_FOUND error.Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking. This operation may "fail open" without warning.

Updates (replaces) autoscaling policy.Disabled check for update_mask, because all updates will be full replacements.

### Method Details

`create(parent, body, x__xgafv=None)`

    Creates new autoscaling policy.

        The object takes the form of:

For example, if max_instances for secondary workers is 0, then only primary workers will be added. The cluster can also be out of balance when created.If weight is not set on any instance group, the cluster will default to equal weight for all groups: the cluster will attempt to maintain an equal number of workers in each group within the configured size bounds for each group. If weight is set for one group only, the cluster will default to zero weight on the unset group. For example if weight is set only on primary workers, the cluster will use primary workers only and no secondary workers.

`testIamPermissions(resource, body, x__xgafv=None)`

    Returns permissions that a caller has on the specified resource. If the resource does not exist, this will return an empty set of permissions, not a NOT_FOUND error.Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking.

          "scaleUpMinWorkerFraction": 3.14, # Optional. Minimum scale-up threshold as a fraction of total cluster size before scaling occurs. For example, in a 20-worker cluster, a threshold of 0.1 means the autoscaler must recommend at least a 2-worker scale-up for the cluster to scale. A threshold of 0 means the autoscaler will scale up on any recommended change.Bounds: 0.0, 1.0. Default: 0.0.

        "secondaryWorkerConfig": { # Configuration for the size bounds of an instance group, including its proportional size to other groups. # Optional. Describes how the autoscaler will operate for secondary workers.

          "maxInstances": 42, # Optional. Maximum number of instances for this group. Required for primary workers. Note that by default, clusters will not use secondary workers. Required for secondary workers if the minimum secondary instances is set.Primary workers - Bounds: [min_instances, ). Required. Secondary workers - Bounds: [min_instances, ). Default: 0.
          "weight": 42, # Optional. Weight for the instance group, which is used to determine the fraction of total workers in the cluster from this instance group. For example, if primary workers have weight 2, and secondary workers have weight 1, the cluster will have approximately 2 primary workers for each secondary worker.The cluster may not reach the specified balance if constrained by min/max bounds or other autoscaling settings. For example, if max_instances for secondary workers is 0, then only primary workers will be added. The cluster can also be out of balance when created.If weight is not set on any instance group, the cluster will default to equal weight for all groups: the cluster will attempt to maintain an equal number of workers in each group within the configured size bounds for each group. If weight is set for one group only, the cluster will default to zero weight on the unset group. For example if weight is set only on primary workers, the cluster will use primary workers only and no secondary workers.
