CreateSnapshot(CreateSnapshotRequest, CallSettings)

public virtual Snapshot CreateSnapshot(CreateSnapshotRequest request, CallSettings callSettings = null)

Creates a snapshot from the requested subscription. Snapshots are used in Seek operations, which allow you to manage message acknowledgments in bulk. That is, you can set the acknowledgment state of messages in an existing subscription to the state captured by a snapshot. If the snapshot already exists, returns ALREADY_EXISTS. If the requested subscription doesn't exist, returns NOT_FOUND. If the backlog in the subscription is too old -- and the resulting snapshot would expire in less than 1 hour -- then FAILED_PRECONDITION is returned. See also the Snapshot.expire_time field. If the name is not provided in the request, the server will assign a random name for this snapshot on the same project as the subscription, conforming to the resource name format. The generated name is populated in the returned Snapshot object. Note that for REST API requests, you must specify a name in the request.

CreateSubscription(SubscriptionName, TopicName, PushConfig, int, CallSettings)

public virtual Subscription CreateSubscription(SubscriptionName name, TopicName topic, PushConfig pushConfig, int ackDeadlineSeconds, CallSettings callSettings = null)

Creates a subscription to a given topic. See the resource name rules. If the subscription already exists, returns ALREADY_EXISTS. If the corresponding topic doesn't exist, returns NOT_FOUND.

Parameters
Name	Description
`name`	`SubscriptionName` Required. The name of the subscription. It must have the format `"projects/{project}/subscriptions/{subscription}"`. `{subscription}` must start with a letter, and contain only letters (`[A-Za-z]`), numbers (`[0-9]`), dashes (`-`), underscores (`_`), periods (`.`), tildes (`~`), plus (`+`) or percent signs (`%`). It must be between 3 and 255 characters in length, and it must not start with `"goog"`.
`topic`	`TopicName` Required. The name of the topic from which this subscription is receiving messages. Format is `projects/{project}/topics/{topic}`. The value of this field will be `_deleted-topic_` if the topic has been deleted.
`pushConfig`	`PushConfig` Optional. If push delivery is used with this subscription, this field is used to configure it.
`ackDeadlineSeconds`	`int` Optional. The approximate amount of time (on a best-effort basis) Pub/Sub waits for the subscriber to acknowledge receipt before resending the message. In the interval after the message is delivered and before it is acknowledged, it is considered to be outstanding. During that time period, the message will not be redelivered (on a best-effort basis). For pull subscriptions, this value is used as the initial value for the ack deadline. To override this value for a given message, call `ModifyAckDeadline` with the corresponding `ack_id` if using non-streaming pull or send the `ack_id` in a `StreamingModifyAckDeadlineRequest` if using streaming pull. The minimum custom deadline you can specify is 10 seconds. The maximum custom deadline you can specify is 600 seconds (10 minutes). If this parameter is 0, a default value of 10 seconds is used. For push delivery, this value is also used to set the request timeout for the call to the push endpoint. If the subscriber never acknowledges the message, the Pub/Sub system will eventually redeliver the message.
`callSettings`	`CallSettings` If not null, applies overrides to this RPC call.

Returns
Type	Description
`Subscription`	The RPC response.

Example

SubscriberServiceApiClient client = SubscriberServiceApiClient.Create();

SubscriptionName subscriptionName = new SubscriptionName(projectId, subscriptionId);
TopicName topicName = new TopicName(projectId, topicId);
Subscription subscription = client.CreateSubscription(
    subscriptionName, topicName, pushConfig: null, ackDeadlineSeconds: 30);
Console.WriteLine($"Created {subscription.Name} subscribed to {subscription.Topic}");

`topic`	`string` Required. The name of the topic from which this subscription is receiving messages. Format is `projects/{project}/topics/{topic}`. The value of this field will be `_deleted-topic_` if the topic has been deleted.
`pushConfig`	`PushConfig` Optional. If push delivery is used with this subscription, this field is used to configure it.
`ackDeadlineSeconds`	`int` Optional. The approximate amount of time (on a best-effort basis) Pub/Sub waits for the subscriber to acknowledge receipt before resending the message.

The minimum custom deadline you can specify is 10 seconds. The maximum custom deadline you can specify is 600 seconds (10 minutes). If this parameter is 0, a default value of 10 seconds is used. For push delivery, this value is also used to set the request timeout for the call to the push endpoint. If the subscriber never acknowledges the message, the Pub/Sub system will eventually redeliver the message.

ModifyAckDeadline(ModifyAckDeadlineRequest, CallSettings)

public virtual void ModifyAckDeadline(ModifyAckDeadlineRequest request, CallSettings callSettings = null)

Modifies the ack deadline for a specific message. This method is useful to indicate that more time is needed to process a message by the subscriber, or to make the message available for redelivery if the processing was interrupted. Note that this does not modify the subscription-level ackDeadlineSeconds used for subsequent messages.

Parameters
Name	Description
`request`	`ModifyAckDeadlineRequest` The request object containing all of the parameters for the API call.
`callSettings`	`CallSettings` If not null, applies overrides to this RPC call.

Example

// Create client
SubscriberServiceApiClient subscriberServiceApiClient = SubscriberServiceApiClient.Create();
// Initialize request argument(s)
ModifyAckDeadlineRequest request = new ModifyAckDeadlineRequest
{
    SubscriptionAsSubscriptionName = SubscriptionName.FromProjectSubscription("[PROJECT]", "[SUBSCRIPTION]"),
    AckDeadlineSeconds = 0,
    AckIds = { "", },
};
// Make the request
subscriberServiceApiClient.ModifyAckDeadline(request);

ModifyAckDeadline(SubscriptionName, IEnumerable<string>, int, CallSettings)

Parameters
Name	Description
`subscription`	`SubscriptionName` Required. The name of the subscription. Format is `projects/{project}/subscriptions/{sub}`.
`ackIds`	`IEnumerablestring` Required. List of acknowledgment IDs.

This typically results in an increase in the rate of message redeliveries (that is, duplicates). The minimum deadline you can specify is 0 seconds. The maximum deadline you can specify in a single request is 600 seconds (10 minutes).
`callSettings`	`CallSettings` If not null, applies overrides to this RPC call.

Example

// Create client
SubscriberServiceApiClient subscriberServiceApiClient = SubscriberServiceApiClient.Create();
// Initialize request argument(s)
SubscriptionName subscription = SubscriptionName.FromProjectSubscription("[PROJECT]", "[SUBSCRIPTION]");

`returnImmediately`	`bool` Optional. If this field set to true, the system will respond immediately even if it there are no messages available to return in the `Pull` response. Otherwise, the system may wait (for a bounded amount of time) until at least one message is available, rather than returning no messages. Warning: setting this field to `true` is discouraged because it adversely impacts the performance of `Pull` operations. We recommend that users do not set this field.
`maxMessages`	`int` Required. The maximum number of messages to return for this request. Must be a positive integer. The Pub/Sub system may return fewer than the number specified.
`callSettings`	`CallSettings` If not null, applies overrides to this RPC call.

{
    // Messages can contain any data. We'll assume that we know this
    // topic publishes UTF-8-encoded text.
    Console.WriteLine($"Message text: {message.Message.Data.ToStringUtf8()}");
}

// Acknowledge the messages after pulling them, so we don't pull them
// a second time later. The ackDeadlineSeconds parameter specified when
// the subscription is created determines how quickly you need to acknowledge
// successfully-pulled messages before they will be redelivered.

The server will close the stream and return the status on any error. The server may close the stream with status UNAVAILABLE to reassign server-side resources, in which case, the client should re-establish the stream. Flow control can be achieved by configuring the underlying RPC channel.

Parameters
Name	Description
`callSettings`	`CallSettings` If not null, applies overrides to this RPC call.
`streamingSettings`	`BidirectionalStreamingSettings` If not null, applies streaming overrides to this RPC call.
