Package memcache is an auto-generated package for the Cloud Memorystore for Memcached API.
Google Cloud Memorystore for Memcached API is used for creating and managing Memcached instances in GCP.
NOTE: This package is in beta. It is not stable, and may be subject to changes.
Use of Context
The ctx passed to NewClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.
To close the open connection, use the Close() method.
For information about setting deadlines, reusing contexts, and more please visit https://pkg.go.dev/cloud.google.com/go .
Functions
func DefaultAuthScopes
func DefaultAuthScopes() [] string
DefaultAuthScopes reports the default set of authentication scopes to use with this package.
ApplyParametersOperation
type ApplyParametersOperation struct {
// contains filtered or unexported fields
}
ApplyParametersOperation manages a long-running operation from ApplyParameters.
func (*ApplyParametersOperation) Done
func (op * ApplyParametersOperation
) Done() bool
Done reports whether the long-running operation has completed.
func (*ApplyParametersOperation) Metadata
func (op * ApplyParametersOperation
) Metadata() (* memcachepb
. OperationMetadata
, 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 (*ApplyParametersOperation) Name
func (op * ApplyParametersOperation
) 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 (op * ApplyParametersOperation
) Poll(ctx context
. Context
, opts ... gax
. CallOption
) (* memcachepb
. 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 (*ApplyParametersOperation) Wait
func (op * ApplyParametersOperation
) Wait(ctx context

CloudMemcacheClient is a client for interacting with Cloud Memorystore for Memcached API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.
Configures and manages Cloud Memorystore for Memcached instances.
The memcache.googleapis.com service implements the Google Cloud Memorystore for Memcached API and defines the following resource model for managing Memorystore Memcached (also called Memcached below) instances:
The service works with a collection of cloud projects, named: /projects/*
Each project has a collection of available locations, named: /locations/*
Each location has a collection of Memcached instances, named: /instances/*
As such, Memcached instances are resources of the form: /projects/{project_id}/locations/{location_id}/instances/{instance_id}
Note that location_id must be a GCP region; for example:
projects/my-memcached-project/locations/us-central1/instances/my-memcached
func NewCloudMemcacheClient
func NewCloudMemcacheClient(ctx context
. Context
, opts ... option

) (* CloudMemcacheClient
, error
