AutoscalingConfig

Autoscaling configuration for an instance.

  },
  "asymmetricAutoscalingOptions": [

    }
  ]
}
Fields
autoscalingLimits

object (AutoscalingLimits)

Required. Autoscaling limits for an instance.
autoscalingTargets

object (AutoscalingTargets)

Required. The autoscaling targets for an instance.
asymmetricAutoscalingOptions[]

object (AsymmetricAutoscalingOption)

Optional. Optional asymmetric autoscaling options. Replicas matching the replica selection criteria will be autoscaled independently from other replicas. The autoscaler will scale the replicas based on the utilization of replicas identified by the replica selection. Replica selections should not overlap with each other.

Other replicas (those do not match any replica selection) will be autoscaled together and will have the same compute capacity allocated to them.

AutoscalingLimits

The autoscaling limits for the instance. Users can define the minimum and maximum compute capacity allocated to the instance, and the autoscaler will only scale within that range. Users can either use nodes or processing units to specify the limits, but should use the same unit to set both the min_limit and maxLimit.

JSON representation 
{

  // Union field min_limit can be only one of the following:
  "minNodes": integer,
  "minProcessingUnits": integer
  // End of list of possible types for union field min_limit.

  // Union field max_limit can be only one of the following:
  "maxNodes": integer,
  "maxProcessingUnits": integer
  // End of list of possible types for union field max_limit.
}
Fields
Union field min_limit. The minimum compute capacity for the instance. min_limit can be only one of the following:
minNodes

integer

Minimum number of nodes allocated to the instance. If set, this number should be greater than or equal to 1.
minProcessingUnits

integer

Minimum number of processing units allocated to the instance. If set, this number should be multiples of 1000.
Union field max_limit. The maximum compute capacity for the instance. The maximum compute capacity should be less than or equal to 10X the minimum compute capacity. max_limit can be only one of the following:
maxNodes

integer

Maximum number of nodes allocated to the instance. If set, this number should be greater than or equal to minNodes.
maxProcessingUnits

integer

Maximum number of processing units allocated to the instance. If set, this number should be multiples of 1000 and be greater than or equal to minProcessingUnits.

AutoscalingTargets

The autoscaling targets for an instance.

JSON representation 
{
  "highPriorityCpuUtilizationPercent": integer,
  "totalCpuUtilizationPercent": integer,
  "storageUtilizationPercent": integer
}
Fields
highPriorityCpuUtilizationPercent

integer

Optional. The target high priority cpu utilization percentage that the autoscaler should be trying to achieve for the instance. This number is on a scale from 0 (no utilization) to 100 (full utilization). The valid range is [10, 90] inclusive. If not specified or set to 0, the autoscaler skips scaling based on high priority CPU utilization.
totalCpuUtilizationPercent

integer

Optional. The target total CPU utilization percentage that the autoscaler should be trying to achieve for the instance. This number is on a scale from 0 (no utilization) to 100 (full utilization). The valid range is [10, 90] inclusive. If not specified or set to 0, the autoscaler skips scaling based on total CPU utilization. If both highPriorityCpuUtilizationPercent and totalCpuUtilizationPercent are specified, the autoscaler provisions the larger of the two required compute capacities to satisfy both targets.
storageUtilizationPercent

integer

Required. The target storage utilization percentage that the autoscaler should be trying to achieve for the instance. This number is on a scale from 0 (no utilization) to 100 (full utilization). The valid range is [10, 99] inclusive.

AsymmetricAutoscalingOption

AsymmetricAutoscalingOption specifies the scaling of replicas identified by the given selection.

JSON representation 
{
  "replicaSelection": {
    object (ReplicaSelection)
  },
  "overrides": {
    object (AutoscalingConfigOverrides)
  }
}
Fields
replicaSelection

object (ReplicaSelection)

Required. Selects the replicas to which this AsymmetricAutoscalingOption applies. Only read-only replicas are supported.
overrides

object (AutoscalingConfigOverrides)

Optional. Overrides applied to the top-level autoscaling configuration for the selected replicas.

AutoscalingConfigOverrides

Overrides the top-level autoscaling configuration for the replicas identified by replicaSelection. All fields in this message are optional. Any unspecified fields will use the corresponding values from the top-level autoscaling configuration.

JSON representation 
{
  "autoscalingLimits": {
    object (AutoscalingLimits)
  },
  "autoscalingTargetHighPriorityCpuUtilizationPercent": integer,
  "autoscalingTargetTotalCpuUtilizationPercent": integer,
  "disableHighPriorityCpuAutoscaling": boolean,
  "disableTotalCpuAutoscaling": boolean
}
Fields
autoscalingLimits

object (AutoscalingLimits)

Optional. If specified, overrides the min/max limit in the top-level autoscaling configuration for the selected replicas.
autoscalingTargetHighPriorityCpuUtilizationPercent

integer

Optional. If specified, overrides the autoscaling target highPriorityCpuUtilizationPercent in the top-level autoscaling configuration for the selected replicas.
autoscalingTargetTotalCpuUtilizationPercent

integer

Optional. If specified, overrides the autoscaling target totalCpuUtilizationPercent in the top-level autoscaling configuration for the selected replicas.
disableHighPriorityCpuAutoscaling

boolean

Optional. If true, disables high priority CPU autoscaling for the selected replicas and ignores highPriorityCpuUtilizationPercent in the top-level autoscaling configuration.

When setting this field to true, setting autoscalingTargetHighPriorityCpuUtilizationPercent field to a non-zero value for the same replica is not supported.

If false, the autoscalingTargetHighPriorityCpuUtilizationPercent field in the replica will be used if set to a non-zero value. Otherwise, the highPriorityCpuUtilizationPercent field in the top-level autoscaling configuration will be used.

Setting both disableHighPriorityCpuAutoscaling and disableTotalCpuAutoscaling to true for the same replica is not supported.
disableTotalCpuAutoscaling

boolean

Optional. If true, disables total CPU autoscaling for the selected replicas and ignores totalCpuUtilizationPercent in the top-level autoscaling configuration.

When setting this field to true, setting autoscalingTargetTotalCpuUtilizationPercent field to a non-zero value for the same replica is not supported.

If false, the autoscalingTargetTotalCpuUtilizationPercent field in the replica will be used if set to a non-zero value. Otherwise, the totalCpuUtilizationPercent field in the top-level autoscaling configuration will be used.

Setting both disableHighPriorityCpuAutoscaling and disableTotalCpuAutoscaling to true for the same replica is not supported.
