Interface InstanceAdminGrpc.AsyncService (6.79.0) 

public static interface InstanceAdminGrpc.AsyncService

Cloud Spanner Instance Admin API The Cloud Spanner Instance Admin API can be used to create, delete, modify and list instances. Instances are dedicated Cloud Spanner serving and storage resources to be used by Cloud Spanner databases. Each instance has a "configuration", which dictates where the serving resources for the Cloud Spanner instance are located (e.g., US-central, Europe). Configurations are created by Google based on resource availability. Cloud Spanner billing is based on the instances that exist and their sizes. After an instance exists, there are no additional per-database or per-operation charges for use of the instance (though there may be additional network bandwidth charges). Instances offer isolation: problems with databases in one instance will not affect other instances. However, within an instance databases can affect each other. For example, if one database in an instance receives a lot of requests and consumes most of the instance resources, fewer resources are available for other databases in that instance, and their performance may suffer.

Methods

createInstance(CreateInstanceRequest request, StreamObserver<Operation> responseObserver)

public default void createInstance(CreateInstanceRequest request, StreamObserver<Operation> responseObserver)

Creates an instance and begins preparing it to begin serving. The returned long-running operation can be used to track the progress of preparing the new instance. The instance name is assigned by the caller. If the named instance already exists, CreateInstance returns ALREADY_EXISTS. Immediately upon completion of this request:

  • The instance is readable via the API, with all requested attributes but no allocated resources. Its state is CREATING. Until completion of the returned operation:
  • Cancelling the operation renders the instance immediately unreadable via the API.
  • The instance can be deleted.
  • All other attempts to modify the instance are rejected. Upon completion of the returned operation:
  • Billing for all successfully-allocated resources begins (some types may have lower than the requested levels).
  • Databases can be created in the instance.
  • The instance's allocated resource levels are readable via the API.
  • The instance's state becomes READY. The returned long-running operation will have a name of the format <instance_name>/operations/<operation_id> and can be used to track creation of the instance. The metadata field type is CreateInstanceMetadata. The response field type is Instance, if successful.
Parameters
Name Description
request CreateInstanceRequest
responseObserver io.grpc.stub.StreamObserver<Operation>

createInstanceConfig(CreateInstanceConfigRequest request, StreamObserver<Operation> responseObserver)

public default void createInstanceConfig(CreateInstanceConfigRequest request, StreamObserver<Operation> responseObserver)

Creates an instance configuration and begins preparing it to be used. The returned long-running operation can be used to track the progress of preparing the new instance configuration. The instance configuration name is assigned by the caller. If the named instance configuration already exists, CreateInstanceConfig returns ALREADY_EXISTS. Immediately after the request returns:

  • The instance configuration is readable via the API, with all requested attributes. The instance configuration's reconciling field is set to true. Its state is CREATING. While the operation is pending:
  • Cancelling the operation renders the instance configuration immediately unreadable via the API.
  • Except for deleting the creating resource, all other attempts to modify the instance configuration are rejected. Upon completion of the returned operation:
  • Instances can be created using the instance configuration.
  • The instance configuration's reconciling field becomes false. Its state becomes READY. The returned long-running operation will have a name of the format <instance_config_name>/operations/<operation_id> and can be used to track creation of the instance configuration. The metadata field type is CreateInstanceConfigMetadata. The response field type is InstanceConfig, if successful. Authorization requires spanner.instanceConfigs.create permission on the resource parent.
Parameters
Name Description
request CreateInstanceConfigRequest
responseObserver io.grpc.stub.StreamObserver<Operation>

createInstancePartition(CreateInstancePartitionRequest request, StreamObserver<Operation> responseObserver)

public default void createInstancePartition(CreateInstancePartitionRequest request, StreamObserver<Operation> responseObserver)

Creates an instance partition and begins preparing it to be used. The returned long-running operation can be used to track the progress of preparing the new instance partition. The instance partition name is assigned by the caller. If the named instance partition already exists, CreateInstancePartition returns ALREADY_EXISTS. Immediately upon completion of this request:

  • The instance partition is readable via the API, with all requested attributes but no allocated resources. Its state is CREATING. Until completion of the returned operation:
  • Cancelling the operation renders the instance partition immediately unreadable via the API.
  • The instance partition can be deleted.
  • All other attempts to modify the instance partition are rejected. Upon completion of the returned operation:
  • Billing for all successfully-allocated resources begins (some types may have lower than the requested levels).
  • Databases can start using this instance partition.
  • The instance partition's allocated resource levels are readable via the API.
  • The instance partition's state becomes READY. The returned long-running operation will have a name of the format <instance_partition_name>/operations/<operation_id> and can be used to track creation of the instance partition. The metadata field type is CreateInstancePartitionMetadata. The response field type is InstancePartition, if successful.

deleteInstance(DeleteInstanceRequest request, StreamObserver<Empty> responseObserver)

public default void deleteInstance(DeleteInstanceRequest request, StreamObserver<Empty> responseObserver)

Deletes an instance. Immediately upon completion of the request:

  • Billing ceases for all of the instance's reserved resources. Soon afterward:
  • The instance and all of its databases immediately and irrevocably disappear from the API. All data in the databases is permanently deleted.

public default void listInstancePartitionOperations(ListInstancePartitionOperationsRequest request, StreamObserver<ListInstancePartitionOperationsResponse> responseObserver)

Lists instance partition long-running operations in the given instance. An instance partition operation has a name of the form projects/<project>/instances/<instance>/instancePartitions/<instance_partition>/operations/<operation>. The long-running operation metadata field type metadata.type_url describes the type of the metadata. Operations returned include those that have completed/failed/canceled within the last 7 days, and pending operations. Operations returned are ordered by operation.metadata.value.start_time in descending order starting from the most recently started operation. Authorization requires spanner.instancePartitionOperations.list permission on the resource parent.

moveInstance(MoveInstanceRequest request, StreamObserver<Operation> responseObserver)

public default void moveInstance(MoveInstanceRequest request, StreamObserver<Operation> responseObserver)

Moves an instance to the target instance configuration. You can use the returned long-running operation to track the progress of moving the instance. MoveInstance returns FAILED_PRECONDITION if the instance meets any of the following criteria:

  • Is undergoing a move to a different instance configuration
  • Has backups
  • Has an ongoing update
  • Contains any CMEK-enabled databases
  • Is a free trial instance While the operation is pending:
  • All other attempts to modify the instance, including changes to its compute capacity, are rejected.
  • The following database and backup admin operations are rejected:
    • DatabaseAdmin.CreateDatabase
    • DatabaseAdmin.UpdateDatabaseDdl (disabled if default_leader is specified in the request.)
    • DatabaseAdmin.RestoreDatabase
    • DatabaseAdmin.CreateBackup
    • DatabaseAdmin.CopyBackup
  • Both the source and target instance configurations are subject to hourly compute and storage charges.
  • The instance might experience higher read-write latencies and a higher transaction abort rate. However, moving an instance doesn't cause any downtime. The returned long-running operation has a name of the format <instance_name>/operations/<operation_id> and can be used to track the move instance operation. The metadata field type is MoveInstanceMetadata. The response field type is Instance, if successful. Cancelling the operation sets its metadata's cancel_time. Cancellation is not immediate because it involves moving any data previously moved to the target instance configuration back to the original instance configuration. You can use this operation to track the progress of the cancellation. Upon successful completion of the cancellation, the operation terminates with CANCELLED status. If not cancelled, upon completion of the returned operation:
  • The instance successfully moves to the target instance configuration.
  • You are billed for compute and storage in target instance configuration. Authorization requires the spanner.instances.update permission on the resource instance. For more details, see Move an instance.
Parameters
Name Description
request MoveInstanceRequest
responseObserver io.grpc.stub.StreamObserver<Operation>

setIamPolicy(SetIamPolicyRequest request, StreamObserver<Policy> responseObserver)

public default void setIamPolicy(SetIamPolicyRequest request, StreamObserver<Policy> responseObserver)

Sets the access control policy on an instance resource. Replaces any existing policy. Authorization requires spanner.instances.setIamPolicy on resource.

Parameters
Name Description
request com.google.iam.v1.SetIamPolicyRequest
responseObserver io.grpc.stub.StreamObserver<com.google.iam.v1.Policy>

testIamPermissions(TestIamPermissionsRequest request, StreamObserver<TestIamPermissionsResponse> responseObserver)

public default void testIamPermissions(TestIamPermissionsRequest request, StreamObserver<TestIamPermissionsResponse> responseObserver)

Returns permissions that the caller has on the specified instance resource. Attempting this RPC on a non-existent Cloud Spanner instance resource will result in a NOT_FOUND error if the user has spanner.instances.list permission on the containing Google Cloud Project. Otherwise returns an empty set of permissions.

Parameters
Name Description
request com.google.iam.v1.TestIamPermissionsRequest
responseObserver io.grpc.stub.StreamObserver<com.google.iam.v1.TestIamPermissionsResponse>

updateInstance(UpdateInstanceRequest request, StreamObserver<Operation> responseObserver)

public default void updateInstance(UpdateInstanceRequest request, StreamObserver<Operation> responseObserver)

Updates an instance, and begins allocating or releasing resources as requested. The returned long-running operation can be used to track the progress of updating the instance. If the named instance does not exist, returns NOT_FOUND. Immediately upon completion of this request:

  • For resource types for which a decrease in the instance's allocation has been requested, billing is based on the newly-requested level. Until completion of the returned operation:
  • Cancelling the operation sets its metadata's cancel_time, and begins restoring resources to their pre-request values. The operation is guaranteed to succeed at undoing all resource changes, after which point it terminates with a CANCELLED status.
  • All other attempts to modify the instance are rejected.
  • Reading the instance via the API continues to give the pre-request resource levels. Upon completion of the returned operation:
  • Billing begins for all successfully-allocated resources (some types may have lower than the requested levels).
  • All newly-reserved resources are available for serving the instance's tables.
  • The instance's new resource levels are readable via the API. The returned long-running operation will have a name of the format <instance_name>/operations/<operation_id> and can be used to track the instance modification. The metadata field type is UpdateInstanceMetadata. The response field type is Instance, if successful. Authorization requires spanner.instances.update permission on the resource name.
Parameters
Name Description
request UpdateInstanceRequest
responseObserver io.grpc.stub.StreamObserver<Operation>

updateInstanceConfig(UpdateInstanceConfigRequest request, StreamObserver<Operation> responseObserver)

public default void updateInstanceConfig(UpdateInstanceConfigRequest request, StreamObserver<Operation> responseObserver)

Updates an instance configuration. The returned long-running operation can be used to track the progress of updating the instance. If the named instance configuration does not exist, returns NOT_FOUND. Only user-managed configurations can be updated. Immediately after the request returns:

  • The instance configuration's reconciling field is set to true. While the operation is pending:
  • Cancelling the operation sets its metadata's cancel_time. The operation is guaranteed to succeed at undoing all changes, after which point it terminates with a CANCELLED status.
  • All other attempts to modify the instance configuration are rejected.
  • Reading the instance configuration via the API continues to give the pre-request values. Upon completion of the returned operation:
  • Creating instances using the instance configuration uses the new values.
  • The new values of the instance configuration are readable via the API.
  • The instance configuration's reconciling field becomes false. The returned long-running operation will have a name of the format <instance_config_name>/operations/<operation_id> and can be used to track the instance configuration modification. The metadata field type is UpdateInstanceConfigMetadata. The response field type is InstanceConfig, if successful. Authorization requires spanner.instanceConfigs.update permission on the resource name.
