Properties

BaseConfig

Base configuration name, e.g. projects//instanceConfigs/nam3, based on which this configuration is created. Only set for user-managed configurations. base_config must refer to a configuration of type GOOGLE_MANAGED in the same project as this configuration.

Declaration
[JsonProperty("baseConfig")]
public virtual string BaseConfig { get; set; }
Property Value
Type Description
string

ConfigType

Output only. Whether this instance configuration is a Google-managed or user-managed configuration.

Declaration
[JsonProperty("configType")]
public virtual string ConfigType { get; set; }
Property Value
Type Description
string

DisplayName

The name of this instance configuration as it appears in UIs.

Declaration
[JsonProperty("displayName")]
public virtual string DisplayName { get; set; }
Property Value
Type Description
string

ETag

etag is used for optimistic concurrency control as a way to help prevent simultaneous updates of a instance configuration from overwriting each other. It is strongly suggested that systems make use of the etag in the read-modify-write cycle to perform instance configuration updates in order to avoid race conditions: An etag is returned in the response which contains instance configurations, and systems are expected to put that etag in the request to update instance configuration to ensure that their change is applied to the same version of the instance configuration. If no etag is provided in the call to update the instance configuration, then the existing instance configuration is overwritten blindly.

Declaration
[JsonProperty("etag")]
public virtual string ETag { get; set; }
Property Value
Type Description
string

FreeInstanceAvailability

Output only. Describes whether free instances are available to be created in this instance configuration.

Declaration
[JsonProperty("freeInstanceAvailability")]
public virtual string FreeInstanceAvailability { get; set; }
Property Value
Type Description
string

Labels

Cloud Labels are a flexible and lightweight mechanism for organizing cloud resources into groups that reflect a customer's organizational needs and deployment strategies. Cloud Labels can be used to filter collections of resources. They can be used to control how resource metrics are aggregated. And they can be used as arguments to policy management rules (e.g. route, firewall, load balancing, etc.). * Label keys must be between 1 and 63 characters long and must conform to the following regular expression: a-z{0,62}. * Label values must be between 0 and 63 characters long and must conform to the regular expression [a-z0-9_-]{0,63}. * No more than 64 labels can be associated with a given resource. See https://goo.gl/xmQnxf for more information on and examples of labels. If you plan to use labels in your own code, please note that additional characters may be allowed in the future. Therefore, you are advised to use an internal label representation, such as JSON, which doesn't rely upon specific characters being disallowed. For example, representing labels as the string: name + "" + value would prove problematic if we were to allow "" in a future release.

Declaration
[JsonProperty("labels")]
public virtual IDictionary<string, string> Labels { get; set; }
Property Value
Type Description
IDictionary<string, string>

LeaderOptions

Allowed values of the "default_leader" schema option for databases in instances that use this instance configuration.

Declaration
[JsonProperty("leaderOptions")]
public virtual IList<string> LeaderOptions { get; set; }
Property Value
Type Description
IList<string>

Name

A unique identifier for the instance configuration. Values are of the form projects//instanceConfigs/a-z*. User instance configuration must start with custom-.

Declaration
[JsonProperty("name")]
public virtual string Name { get; set; }
Property Value
Type Description
string

OptionalReplicas

Output only. The available optional replicas to choose from for user-managed configurations. Populated for Google-managed configurations.

Declaration
[JsonProperty("optionalReplicas")]
public virtual IList<ReplicaInfo> OptionalReplicas { get; set; }
Property Value
Type Description
IList<ReplicaInfo>

QuorumType

Output only. The QuorumType of the instance configuration.

Declaration
[JsonProperty("quorumType")]
public virtual string QuorumType { get; set; }
Property Value
Type Description
string

Reconciling

Output only. If true, the instance configuration is being created or updated. If false, there are no ongoing operations for the instance configuration.

Declaration
[JsonProperty("reconciling")]
public virtual bool? Reconciling { get; set; }
Property Value
Type Description
bool?

Replicas

The geographic placement of nodes in this instance configuration and their replication properties. To create user-managed configurations, input replicas must include all replicas in replicas of the base_config and include one or more replicas in the optional_replicas of the base_config.

Declaration
[JsonProperty("replicas")]
public virtual IList<ReplicaInfo> Replicas { get; set; }
Property Value
Type Description
IList<ReplicaInfo>

State

Output only. The current instance configuration state. Applicable only for USER_MANAGED configurations.

Declaration
[JsonProperty("state")]
public virtual string State { get; set; }
Property Value
Type Description
string

StorageLimitPerProcessingUnit

Output only. The storage limit in bytes per processing unit.

Declaration
[JsonProperty("storageLimitPerProcessingUnit")]
public virtual long? StorageLimitPerProcessingUnit { get; set; }
Property Value
Type Description
long?
