Method get
Returns the specified subcluster.
To get the list of all available subclusters, make a list request.

A Data Proc subcluster. For details about the concept, see documentation.
| Field | Description |
|---|---|
| id | string ID of the subcluster. Generated at creation time. |
| clusterId | string ID of the Data Proc cluster that the subcluster belongs to. |
| createdAt | string (date-time) Creation timestamp. String in RFC3339 text format. |
| name | string Name of the subcluster. The name is unique within the cluster. The string length in characters must be 1-63. |
| role | string Role that is fulfilled by hosts of the subcluster.
Master can run the following services, depending on the requested components:
DATANODE can run the following services, depending on the requested components:
COMPUTENODE can run the following services, depending on the requested components:
|
| resources | object Resources allocated for each host in the subcluster. |
| resources. resourcePresetId |
string ID of the resource preset for computational resources available to a host (CPU, memory etc.). All available presets are listed in the documentation. |
| resources. diskTypeId |
string Type of the storage environment for the host. Possible values:
|
| resources. diskSize |
string (int64) Volume of the storage available to a host, in bytes. |
| subnetId | string ID of the VPC subnet used for hosts in the subcluster. |
| hostsCount | string (int64) Number of hosts in the subcluster. |
| autoscalingConfig | object Configuration for instance group based subclusters |
| autoscalingConfig. maxHostsCount |
string (int64) Upper limit for total instance subcluster count. Acceptable values are 1 to 100, inclusive. |
| autoscalingConfig. preemptible |
boolean (boolean) Preemptible instances are stopped at least once every 24 hours, and can be stopped at any time if their resources are needed by Compute. For more information, see Preemptible Virtual Machines. |
| autoscalingConfig. measurementDuration |
string Required. Time in seconds allotted for averaging metrics. Acceptable values are 60 seconds to 600 seconds, inclusive. |
| autoscalingConfig. warmupDuration |
string The warmup time of the instance in seconds. During this time, traffic is sent to the instance, but instance metrics are not collected. The maximum value is 600 seconds. |
| autoscalingConfig. stabilizationDuration |
string Minimum amount of time in seconds allotted for monitoring before Instance Groups can reduce the number of instances in the group. During this time, the group size doesn't decrease, even if the new metric values indicate that it should. Acceptable values are 60 seconds to 1800 seconds, inclusive. |
| autoscalingConfig. cpuUtilizationTarget |
number (double) Defines an autoscaling rule based on the average CPU utilization of the instance group. Acceptable values are 10 to 100, inclusive. |
| autoscalingConfig. decommissionTimeout |
string (int64) Timeout to gracefully decommission nodes during downscaling. In seconds. Default value: 120 Acceptable values are 0 to 86400, inclusive. |
| instanceGroupId | string ID of Compute Instance Group for autoscaling subclusters |
