Pub/Sub Lite API v1 - Package cloud.google.com/go/pubsublite/apiv1 (v1.8.0)

Package pubsublite is an auto-generated package for the Pub/Sub Lite API.

General documentation

For information about setting deadlines, reusing contexts, and more please visit https://pkg.go.dev/cloud.google.com/go.

Example usage

To get started with this package, create a client.

ctx := context.Background()
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in:
//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
c, err := pubsublite.NewAdminClient(ctx)
if err != nil {
    // TODO: Handle error.
}
defer c.Close()

The client will use your default application credentials. Clients should be reused instead of created as needed. The methods of Client are safe for concurrent use by multiple goroutines. The returned client must be Closed when it is done being used.

Using the Client

The following is an example of making an API call with the newly created client.

ctx := context.Background()
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in:
//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
c, err := pubsublite.NewAdminClient(ctx)
if err != nil {
    // TODO: Handle error.
}
defer c.Close()

req := &pubsublitepb.CreateTopicRequest{
    // TODO: Fill request struct fields.
    // See https://pkg.go.dev/cloud.google.com/go/pubsublite/apiv1/pubsublitepb#CreateTopicRequest.
}
resp, err := c.CreateTopic(ctx, req)
if err != nil {
    // TODO: Handle error.
}
// TODO: Use resp.
_ = resp

Use of Context

The ctx passed to NewAdminClient 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.

Functions

func DefaultAuthScopes

func DefaultAuthScopes() []string

DefaultAuthScopes reports the default set of authentication scopes to use with this package.

AdminCallOptions

type AdminCallOptions struct {
	CreateTopic            []gax.CallOption
	GetTopic               []gax.CallOption
	GetTopicPartitions     []gax.CallOption
	ListTopics             []gax.CallOption
	UpdateTopic            []gax.CallOption
	DeleteTopic            []gax.CallOption
	ListTopicSubscriptions []gax.CallOption
	CreateSubscription     []gax.CallOption
	GetSubscription        []gax.CallOption
	ListSubscriptions      []gax.CallOption
	UpdateSubscription     []gax.CallOption
	DeleteSubscription     []gax.CallOption
	SeekSubscription       []gax.CallOption
	CreateReservation      []gax.CallOption
	GetReservation         []gax.CallOption
	ListReservations       []gax.CallOption
	UpdateReservation      []gax.CallOption
	DeleteReservation      []gax.CallOption
	ListReservationTopics  []gax.CallOption
	CancelOperation        []gax.CallOption
	DeleteOperation        []gax.CallOption
	GetOperation           []gax.CallOption
	ListOperations         []gax.CallOption
}

AdminCallOptions contains the retry settings for each method of AdminClient.

AdminClient

type AdminClient struct {

	// The call options for this service.
	CallOptions *AdminCallOptions

	// LROClient is used internally to handle long-running operations.
	// It is exposed so that its CallOptions can be modified if required.
	// Users should not Close this client.
	LROClient *lroauto.OperationsClient
	// contains filtered or unexported fields
}

AdminClient is a client for interacting with Pub/Sub Lite API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

The service that a client application uses to manage topics and subscriptions, such creating, listing, and deleting topics and subscriptions.

func NewAdminClient

func NewAdminClient(ctx context.Context, opts ...option.ClientOption) (*AdminClient, error)

NewAdminClient creates a new admin service client based on gRPC. The returned client must be Closed when it is done being used to clean up its underlying connections.

The service that a client application uses to manage topics and subscriptions, such creating, listing, and deleting topics and subscriptions.

Example

package main

func (*AdminClient) SeekSubscription

SeekSubscription performs an out-of-band seek for a subscription to a specified target, which may be timestamps or named positions within the message backlog. Seek translates these targets to cursors for each partition and orchestrates subscribers to start consuming messages from these seek cursors.

If an operation is returned, the seek has been registered and subscribers will eventually receive messages from the seek cursors (i.e. eventual consistency), as long as they are using a minimum supported client library version and not a system that tracks cursors independently of Pub/Sub Lite (e.g. Apache Beam, Dataflow, Spark). The seek operation will fail for unsupported clients.

If clients would like to know when subscribers react to the seek (or not), they can poll the operation. The seek operation will succeed and complete once subscribers are ready to receive messages from the seek cursors for all partitions of the topic. This means that the seek operation will not complete until all subscribers come online.

If the previous seek operation has not yet completed, it will be aborted and the new invocation of seek will supersede it.

package main

import (
	"context"

	pubsublite "cloud.google.com/go/pubsublite/apiv1"

	pubsublitepb "cloud.google.com/go/pubsublite/apiv1/pubsublitepb"

	// contains filtered or unexported fields
}

SubscriptionIterator manages a stream of *pubsublitepb.Subscription.

func (*SubscriptionIterator) Next

Next returns the next result. Its second return value is iterator.Done if there are no more results. Once Next returns Done, all subsequent calls will return Done.

func (*SubscriptionIterator) PageInfo

func (it *SubscriptionIterator) PageInfo() *iterator.PageInfo

TopicStatsClient

type TopicStatsClient struct {

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

TopicStatsClient is a client for interacting with Pub/Sub Lite API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

This service allows users to get stats about messages in their topic.

func NewTopicStatsClient

func NewTopicStatsClient(ctx context.Context, opts ...option.ClientOption) (*TopicStatsClient, error)

NewTopicStatsClient creates a new topic stats service client based on gRPC. The returned client must be Closed when it is done being used to clean up its underlying connections.

This service allows users to get stats about messages in their topic.

Example

package main

import (
	"context"

	pubsublite "cloud.google.com/go/pubsublite/apiv1"
)

func main() {

	// It will require modifications to work:
	// - It may require correct/in-range values for request initialization.
	// - It may require specifying regional endpoints when creating the service client as shown in:
	//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
	c, err := pubsublite.NewTopicStatsClient(ctx)

func (*TopicStatsClient) Close

func (c *TopicStatsClient) Close() error

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

func (*TopicStatsClient) ComputeHeadCursor

ComputeHeadCursor compute the head cursor for the partition. The head cursor’s offset is guaranteed to be less than or equal to all messages which have not yet been acknowledged as published, and greater than the offset of any message whose publish has already been acknowledged. It is zero if there have never been messages in the partition.

Example

package main
