func InstanceAdminInstanceConfigPath Uses

func InstanceAdminInstanceConfigPath(project, instanceConfig string) string

InstanceAdminInstanceConfigPath returns the path for the instance config resource.

func InstanceAdminInstancePath Uses

func InstanceAdminInstancePath(project, instance string) string

InstanceAdminInstancePath returns the path for the instance resource.

func InstanceAdminProjectPath Uses

func InstanceAdminProjectPath(project string) string

type CreateInstanceOperation Uses

type CreateInstanceOperation struct {
    // contains filtered or unexported fields
}

CreateInstanceOperation manages a long-running operation from CreateInstance.

func (*CreateInstanceOperation) Done Uses

func (op *CreateInstanceOperation) Done() bool

Done reports whether the long-running operation has completed.

func (*CreateInstanceOperation) Metadata Uses

func (op *CreateInstanceOperation) Metadata() (*instancepb.CreateInstanceMetadata, error)

Metadata returns metadata associated with the long-running operation. Metadata itself does not contact the server, but Poll does. To get the latest metadata, call this method after a successful call to Poll. If the metadata is not available, the returned metadata and error are both nil.

func (*CreateInstanceOperation) Name Uses

func (op *CreateInstanceOperation) Name() string

Name returns the name of the long-running operation. The name is assigned by the server and is unique within the service from which the operation is created.

func (*CreateInstanceOperation) Poll Uses

func (op *CreateInstanceOperation) Poll(ctx context.Context, opts ...gax.CallOption) (*instancepb.Instance, error)

Poll fetches the latest state of the long-running operation.

Poll also fetches the latest metadata, which can be retrieved by Metadata.

If Poll fails, the error is returned and op is unmodified. If Poll succeeds and the operation has completed with failure, the error is returned and op.Done will return true. If Poll succeeds and the operation has completed successfully, op.Done will return true, and the response of the operation is returned. If Poll succeeds and the operation has not completed, the returned response and error are both nil.

func (*CreateInstanceOperation) Wait Uses

func (op *CreateInstanceOperation) Wait(ctx context.Context, opts ...gax.CallOption) (*instancepb.Instance, error)

Wait blocks until the long-running operation is completed, returning the response and any errors encountered.

See documentation of Poll for error-handling information.

    GetIamPolicy        []gax.CallOption
    TestIamPermissions  []gax.CallOption
}

InstanceAdminCallOptions contains the retry settings for each method of InstanceAdminClient.

type InstanceAdminClient Uses

type InstanceAdminClient struct {

    // LROClient is used internally to handle longrunning operations.
    // It is exposed so that its CallOptions can be modified if required.
    // Users should not Close this client.
    LROClient *lroauto.OperationsClient

    // The call options for this service.
    CallOptions *InstanceAdminCallOptions
    // contains filtered or unexported fields
}

InstanceAdminClient is a client for interacting with Cloud Spanner Instance Admin API.

func NewInstanceAdminClient Uses

func NewInstanceAdminClient(ctx context.Context, opts ...option.ClientOption) (*InstanceAdminClient, error)

NewInstanceAdminClient creates a new instance admin client.

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.

Code:

ctx := context.Background()
c, err := instance.NewInstanceAdminClient(ctx)
if err != nil {
    // TODO: Handle error.
}
// TODO: Use client.
_ = c

func (*InstanceAdminClient) Close Uses

func (c *InstanceAdminClient) Close() error

Close closes the connection to the API service. The user should invoke this when the client is no longer required.

func (*InstanceAdminClient) Connection Uses

func (c *InstanceAdminClient) Connection() *grpc.ClientConn

Connection returns the client's connection to the API service.

func (*InstanceAdminClient) CreateInstance Uses

func (c *InstanceAdminClient) CreateInstance(ctx context.Context, req *instancepb.CreateInstanceRequest, opts ...gax.CallOption) (*CreateInstanceOperation, error)

CreateInstance creates an instance and begins preparing it to begin serving. The returned [long-running operation][google.longrunning.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][google.longrunning.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][google.longrunning.Operation.metadata] field type is [CreateInstanceMetadata][google.spanner.admin.instance.v1.CreateInstanceMetadata]. The [response][google.longrunning.Operation.response] field type is [Instance][google.spanner.admin.instance.v1.Instance], if successful.

Code:

ctx := context.Background()
c, err := instance.NewInstanceAdminClient(ctx)
if err != nil {
    // TODO: Handle error.
}

req := &instancepb.CreateInstanceRequest{
// TODO: Fill request struct fields.
}
op, err := c.CreateInstance(ctx, req)
if err != nil {
    // TODO: Handle error.
}

resp, err := op.Wait(ctx)
if err != nil {
    // TODO: Handle error.
}
// TODO: Use resp.
_ = resp

func (*InstanceAdminClient) CreateInstanceOperation Uses

func (c *InstanceAdminClient) CreateInstanceOperation(name string) *CreateInstanceOperation

CreateInstanceOperation returns a new CreateInstanceOperation from a given name. The name must be that of a previously created CreateInstanceOperation, possibly from a different process.

func (*InstanceAdminClient) DeleteInstance Uses

func (c *InstanceAdminClient) DeleteInstance(ctx context.Context, req *instancepb.DeleteInstanceRequest, opts ...gax.CallOption) error

DeleteInstance 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.

Code:

ctx := context.Background()
c, err := instance.NewInstanceAdminClient(ctx)
if err != nil {
    // TODO: Handle error.
}

req := &instancepb.DeleteInstanceRequest{
// TODO: Fill request struct fields.
}
err = c.DeleteInstance(ctx, req)
if err != nil {
    // TODO: Handle error.
}

func (*InstanceAdminClient) GetIamPolicy Uses

func (c *InstanceAdminClient) GetIamPolicy(ctx context.Context, req *iampb.GetIamPolicyRequest, opts ...gax.CallOption) (*iampb.Policy, error)

func (*InstanceAdminClient) SetIamPolicy Uses

func (c *InstanceAdminClient) SetIamPolicy(ctx context.Context, req *iampb.SetIamPolicyRequest, opts ...gax.CallOption) (*iampb.Policy, error)

SetIamPolicy sets the access control policy on an instance resource. Replaces any existing policy.

Authorization requires spanner.instances.setIamPolicy on [resource][google.iam.v1.SetIamPolicyRequest.resource].

Code:

ctx := context.Background()
c, err := instance.NewInstanceAdminClient(ctx)
if err != nil {
    // TODO: Handle error.
}

func (*InstanceAdminClient) TestIamPermissions Uses

func (c *InstanceAdminClient) TestIamPermissions(ctx context.Context, req *iampb.TestIamPermissionsRequest, opts ...gax.CallOption) (*iampb.TestIamPermissionsResponse, error)

TestIamPermissions 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.

Code:

ctx := context.Background()
c, err := instance.NewInstanceAdminClient(ctx)
if err != nil {
    // TODO: Handle error.
}

req := &iampb.TestIamPermissionsRequest{

func (*InstanceAdminClient) UpdateInstance Uses

func (c *InstanceAdminClient) UpdateInstance(ctx context.Context, req *instancepb.UpdateInstanceRequest, opts ...gax.CallOption) (*UpdateInstanceOperation, error)

UpdateInstance updates an instance, and begins allocating or releasing resources as requested. The returned [long-running operation][google.longrunning.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][google.spanner.admin.instance.v1.UpdateInstanceMetadata.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][google.longrunning.Operation] will have a name of the format <instance_name>/operations/<operation_id> and can be used to track the instance modification. The [metadata][google.longrunning.Operation.metadata] field type is [UpdateInstanceMetadata][google.spanner.admin.instance.v1.UpdateInstanceMetadata]. The [response][google.longrunning.Operation.response] field type is [Instance][google.spanner.admin.instance.v1.Instance], if successful.

Authorization requires spanner.instances.update permission on resource [name][google.spanner.admin.instance.v1.Instance.name].

Code:

ctx := context.Background()
c, err := instance.NewInstanceAdminClient(ctx)
if err != nil {
    // TODO: Handle error.
}

req := &instancepb.UpdateInstanceRequest{
// TODO: Fill request struct fields.
}
op, err := c.UpdateInstance(ctx, req)
if err != nil {
    // TODO: Handle error.
