Class Instance (0.2.1) 

Instance(mapping=None, *, ignore_unknown_fields=False, **kwargs)

An Instance is a computing unit that an end customer can connect to. It's the main unit of computing resources in AlloyDB.

Attributes

NameDescription
name str
Output only. The name of the instance resource with the format: - projects/{project}/locations/{region}/clusters/{cluster_id}/instances/{instance_id} where the cluster and instance ID segments should satisfy the regex expression [a-z]([a-z0-9-]{0,61}[a-z0-9])?, e.g. 1-63 characters of lowercase letters, numbers, and dashes, starting with a letter, and ending with a letter or number. For more details see https://google.aip.dev/122. The prefix of the instance resource name is the name of the parent resource: - projects/{project}/locations/{region}/clusters/{cluster_id}
display_name str
User-settable and human-readable display name for the Instance.
uid str
Output only. The system-generated UID of the resource. The UID is assigned when the resource is created, and it is retained until it is deleted.
create_time google.protobuf.timestamp_pb2.Timestamp
Output only. Create time stamp
update_time google.protobuf.timestamp_pb2.Timestamp
Output only. Update time stamp
delete_time google.protobuf.timestamp_pb2.Timestamp
Output only. Delete time stamp
labels MutableMapping[str, str]
Labels as key value pairs
state google.cloud.alloydb_v1alpha.types.Instance.State
Output only. The current serving state of the instance.
instance_type google.cloud.alloydb_v1alpha.types.Instance.InstanceType
Required. The type of the instance. Specified at creation time.
machine_config google.cloud.alloydb_v1alpha.types.Instance.MachineConfig
Configurations for the machines that host the underlying database engine.
availability_type google.cloud.alloydb_v1alpha.types.Instance.AvailabilityType
Availability type of an Instance. If empty, defaults to REGIONAL for primary instances. For read pools, availability_type is always UNSPECIFIED. Instances in the read pools are evenly distributed across available zones within the region (i.e. read pools with more than one node will have a node in at least two zones).
gce_zone str
The Compute Engine zone that the instance should serve from, per https://cloud.google.com/compute/docs/regions-zones This can ONLY be specified for ZONAL instances. If present for a REGIONAL instance, an error will be thrown. If this is absent for a ZONAL instance, instance is created in a random zone with available capacity.
database_flags MutableMapping[str, str]
Database flags. Set at instance level. - They are copied from primary instance on read instance creation. - Read instances can set new or override existing flags that are relevant for reads, e.g. for enabling columnar cache on a read instance. Flags set on read instance may or may not be present on primary. This is a list of "key": "value" pairs. "key": The name of the flag. These flags are passed at instance setup time, so include both server options and system variables for Postgres. Flags are specified with underscores, not hyphens. "value": The value of the flag. Booleans are set to **on** for true and **off** for false. This field must be omitted if the flag doesn't take a value.
writable_node google.cloud.alloydb_v1alpha.types.Instance.Node
Output only. This is set for the read-write VM of the PRIMARY instance only.
nodes MutableSequence[google.cloud.alloydb_v1alpha.types.Instance.Node]
Output only. List of available read-only VMs in this instance, including the standby for a PRIMARY instance.
query_insights_config google.cloud.alloydb_v1alpha.types.Instance.QueryInsightsInstanceConfig
Configuration for query insights.
read_pool_config google.cloud.alloydb_v1alpha.types.Instance.ReadPoolConfig
Read pool specific config.
ip_address str
Output only. The IP address for the Instance. This is the connection endpoint for an end-user application.
reconciling bool
Output only. Reconciling (https://google.aip.dev/128#reconciliation). Set to true if the current state of Instance does not match the user's intended state, and the service is actively updating the resource to reconcile them. This can happen due to user-triggered updates or system actions like failover or maintenance.
etag str
For Resource freshness validation (https://google.aip.dev/154)
annotations MutableMapping[str, str]
Annotations to allow client tools to store small amount of arbitrary data. This is distinct from labels. https://google.aip.dev/128
update_policy google.cloud.alloydb_v1alpha.types.Instance.UpdatePolicy
Update policy that will be applied during instance update. This field is not persisted when you update the instance. To use a non-default update policy, you must specify explicitly specify the value in each update request.

Classes

AnnotationsEntry

AnnotationsEntry(mapping=None, *, ignore_unknown_fields=False, **kwargs)

The abstract base class for a message.

Parameters
NameDescription
kwargs dict

Keys and values corresponding to the fields of the message.

mapping Union[dict, .Message]

A dictionary or message to be used to determine the values for this message.

ignore_unknown_fields Optional(bool)

If True, do not raise errors for unknown fields. Only applied if mapping is a mapping type or there are keyword parameters.

AvailabilityType

AvailabilityType(value)

The Availability type of an instance. Potential values:

  • ZONAL: The instance serves data from only one zone. Outages in that zone affect instance availability.
  • REGIONAL: The instance can serve data from more than one zone in a region (it is highly available).

Values: AVAILABILITY_TYPE_UNSPECIFIED (0): This is an unknown Availability type. ZONAL (1): Zonal available instance. REGIONAL (2): Regional (or Highly) available instance.

DatabaseFlagsEntry

DatabaseFlagsEntry(mapping=None, *, ignore_unknown_fields=False, **kwargs)

The abstract base class for a message.

Parameters
NameDescription
kwargs dict

Keys and values corresponding to the fields of the message.

mapping Union[dict, .Message]

A dictionary or message to be used to determine the values for this message.

ignore_unknown_fields Optional(bool)

If True, do not raise errors for unknown fields. Only applied if mapping is a mapping type or there are keyword parameters.

InstanceType

InstanceType(value)

Type of an Instance

Values: INSTANCE_TYPE_UNSPECIFIED (0): The type of the instance is unknown. PRIMARY (1): PRIMARY instances support read and write operations. READ_POOL (2): READ POOL instances support read operations only. Each read pool instance consists of one or more homogeneous nodes.

    -  Read pool of size 1 can only have zonal availability.
    -  Read pools with node count of 2 or more can have regional
       availability (nodes are present in 2 or more zones in a
       region).

    SECONDARY instances support read operations
    only. SECONDARY instance is a cross-region read
    replica

Keeping that index unused in case that state also needs to exposed via consumer apis in future. The instance has been configured to sync data from some other source. PROMOTING (9): The instance is being promoted.
