Class Cluster (2.43.0) 

public class Cluster

A cluster represents the actual Cloud Bigtable service. Each cluster belongs to a single Cloud Bigtable instance, and an instance can have up to 2 clusters. When your application sends requests to a Cloud Bigtable instance, those requests are actually handled by one of the clusters in the instance.

Overrides

getAutoscalingCpuPercentageTarget()

public int getAutoscalingCpuPercentageTarget()

Get the cpu utilization that the Autoscaler should be trying to achieve. This number is on a scale from 0 (no utilization) to 100 (total utilization).

Returns
Type Description
int

getAutoscalingMaxServeNodes()

public int getAutoscalingMaxServeNodes()

Get the maximum number of nodes to scale up to.

Returns
Type Description
int

getAutoscalingMinServeNodes()

public int getAutoscalingMinServeNodes()

Get the minimum number of nodes to scale down to.

Returns
Type Description
int

getId()

public String getId()

Gets the cluster's id.

Returns
Type Description
String

getInstanceId()

public String getInstanceId()

Gets the instance id.

Returns
Type Description
String

getKmsKeyName()

public String getKmsKeyName()

Google Cloud Key Management Service (KMS) settings for a CMEK-protected Bigtable cluster. This returns the full resource name of the Cloud KMS key in the format projects/{key_project_id}/locations/{location}/keyRings/{ring_name}/cryptoKeys/{key_name}

Returns
Type Description
String

getServeNodes()

public int getServeNodes()

Get the number of nodes allocated to this cluster. More nodes enable higher throughput and more consistent performance.

Returns
Type Description
int

getState()

public Cluster.State getState()

Gets the current state of the cluster

Returns
Type Description
Cluster.State

getStorageType()

public StorageType getStorageType()

The type of storage used by this cluster to serve its parent instance's tables, unless explicitly overridden.

Returns
Type Description
StorageType

getStorageUtilizationGibPerNode()

public int getStorageUtilizationGibPerNode()

Get the storage utilization that the Autoscaler should be trying to achieve. This number is limited between 2560 (2.5TiB) and 5120 (5TiB) for a SSD cluster and between 8192 (8TiB) and 16384 (16TiB) for an HDD cluster; otherwise it will return INVALID_ARGUMENT error. If this value is set to 0, it will be treated as if it were set to the default value: 2560 for SSD, 8192 for HDD.

Returns
Type Description
int

getZone()

public String getZone()

Get the zone where this cluster is located.

Returns
Type Description
String

hashCode()

public int hashCode()
Returns
