Instance Method Details

#acknowledge(request, options = nil) ⇒ ::Google::Protobuf::Empty #acknowledge(subscription: nil, ack_ids: nil) ⇒ ::Google::Protobuf::Empty

Acknowledges the messages associated with the ack_ids in the AcknowledgeRequest. The Pub/Sub system can remove the relevant messages from the subscription.

Acknowledging a message whose ack deadline has expired may succeed, but such a message may be redelivered later. Acknowledging a message more than once will not result in an error.

Overloads:

  • #acknowledge(request, options = nil) ⇒ ::Google::Protobuf::Empty

    Pass arguments to acknowledge via a request object, either of type AcknowledgeRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::PubSub::V1::AcknowledgeRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #acknowledge(subscription: nil, ack_ids: nil) ⇒ ::Google::Protobuf::Empty

    Pass arguments to acknowledge via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • subscription (::String) (defaults to: nil) —

      Required. The subscription whose message is being acknowledged. Format is projects/{project}/subscriptions/{sub}.

    • ack_ids (::Array<::String>) (defaults to: nil) —

      Required. The acknowledgment ID for the messages being acknowledged that was returned by the Pub/Sub system in the Pull response. Must not be empty.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

#configure {|config| ... } ⇒ Client::Configuration

Configure the Subscriber Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on configure.

See Configuration for a description of the configuration fields.

Yields:

  • (config) —

    Configure the Client client.

#create_snapshot(request, options = nil) ⇒ ::Google::Cloud::PubSub::V1::Snapshot #create_snapshot(name: nil, subscription: nil, labels: nil) ⇒ ::Google::Cloud::PubSub::V1::Snapshot

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.

Overloads:

  • #create_snapshot(request, options = nil) ⇒ ::Google::Cloud::PubSub::V1::Snapshot

    Pass arguments to create_snapshot via a request object, either of type CreateSnapshotRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::PubSub::V1::CreateSnapshotRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #create_snapshot(name: nil, subscription: nil, labels: nil) ⇒ ::Google::Cloud::PubSub::V1::Snapshot

    Pass arguments to create_snapshot via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • name (::String) (defaults to: nil) —

      Required. User-provided name for this snapshot. 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. Note that for REST API requests, you must specify a name. See the resource name rules. Format is projects/{project}/snapshots/{snap}.

    • subscription (::String) (defaults to: nil) —

      Required. The subscription whose backlog the snapshot retains. Specifically, the created snapshot is guaranteed to retain: (a) The existing backlog on the subscription. More precisely, this is defined as the messages in the subscription's backlog that are unacknowledged upon the successful completion of the CreateSnapshot request; as well as: (b) Any messages published to the subscription's topic following the successful completion of the CreateSnapshot request. Format is projects/{project}/subscriptions/{sub}.

    • labels (::Hash{::String => ::String}) (defaults to: nil) —

      See Creating and managing labels.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

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.

If the name is not provided in the request, the server will assign a random name for this subscription on the same project as the topic, conforming to the resource name format. The generated name is populated in the returned Subscription object. Note that for REST API requests, you must specify a name in the request.

Overloads:

  • #create_subscription(request, options = nil) ⇒ ::Google::Cloud::PubSub::V1::Subscription

    Pass arguments to create_subscription via a request object, either of type Google::Cloud::PubSub::V1::Subscription or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::PubSub::V1::Subscription, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #create_subscription(name: nil, topic: nil, push_config: nil, ack_deadline_seconds: nil, retain_acked_messages: nil, message_retention_duration: nil, labels: nil, enable_message_ordering: nil, expiration_policy: nil, filter: nil, dead_letter_policy: nil, retry_policy: nil, detached: nil) ⇒ ::Google::Cloud::PubSub::V1::Subscription

    Pass arguments to create_subscription via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • name (::String) (defaults to: nil) —

      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 (::String) (defaults to: nil) —

      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.

    • push_config (::Google::Cloud::PubSub::V1::PushConfig, ::Hash) (defaults to: nil) —

      If push delivery is used with this subscription, this field is used to configure it. An empty pushConfig signifies that the subscriber will pull and ack messages using API methods.

    • ack_deadline_seconds (::Integer) (defaults to: nil) —

      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.

    • retain_acked_messages (::Boolean) (defaults to: nil) —

      Indicates whether to retain acknowledged messages. If true, then messages are not expunged from the subscription's backlog, even if they are acknowledged, until they fall out of the message_retention_duration window. This must be true if you would like to Seek to a timestamp.

    • message_retention_duration (::Google::Protobuf::Duration, ::Hash) (defaults to: nil) —

      How long to retain unacknowledged messages in the subscription's backlog, from the moment a message is published. If retain_acked_messages is true, then this also configures the retention of acknowledged messages, and thus configures how far back in time a Seek can be done. Defaults to 7 days. Cannot be more than 7 days or less than 10 minutes.

    • labels (::Hash{::String => ::String}) (defaults to: nil) —

      See Creating and managing labels.

    • enable_message_ordering (::Boolean) (defaults to: nil) —

      If true, messages published with the same ordering_key in PubsubMessage will be delivered to the subscribers in the order in which they are received by the Pub/Sub system. Otherwise, they may be delivered in any order.

    • expiration_policy (::Google::Cloud::PubSub::V1::ExpirationPolicy, ::Hash) (defaults to: nil) —

      A policy that specifies the conditions for this subscription's expiration. A subscription is considered active as long as any connected subscriber is successfully consuming messages from the subscription or is issuing operations on the subscription. If expiration_policy is not set, a default policy with ttl of 31 days will be used. The minimum allowed value for expiration_policy.ttl is 1 day.

    • filter (::String) (defaults to: nil) —

      An expression written in the Pub/Sub filter language. If non-empty, then only PubsubMessages whose attributes field matches the filter are delivered on this subscription. If empty, then no messages are filtered out.

    • dead_letter_policy (::Google::Cloud::PubSub::V1::DeadLetterPolicy, ::Hash) (defaults to: nil) —

      A policy that specifies the conditions for dead lettering messages in this subscription. If dead_letter_policy is not set, dead lettering is disabled.

      The Cloud Pub/Sub service account associated with this subscriptions's parent project (i.e., service-{project_number}@gcp-sa-pubsub.iam.gserviceaccount.com) must have permission to Acknowledge() messages on this subscription.

    • retry_policy (::Google::Cloud::PubSub::V1::RetryPolicy, ::Hash) (defaults to: nil) —

      A policy that specifies how Pub/Sub retries message delivery for this subscription.

      If not set, the default retry policy is applied. This generally implies that messages will be retried as soon as possible for healthy subscribers. RetryPolicy will be triggered on NACKs or acknowledgement deadline exceeded events for a given message.

    • detached (::Boolean) (defaults to: nil) —

      Indicates whether the subscription is detached from its topic. Detached subscriptions don't receive messages from their topic and don't retain any backlog. Pull and StreamingPull requests will return FAILED_PRECONDITION. If the subscription is a push subscription, pushes to the endpoint will not be made.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

#delete_snapshot(request, options = nil) ⇒ ::Google::Protobuf::Empty #delete_snapshot(snapshot: nil) ⇒ ::Google::Protobuf::Empty

Removes an existing snapshot. 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. When the snapshot is deleted, all messages retained in the snapshot are immediately dropped. After a snapshot is deleted, a new one may be created with the same name, but the new one has no association with the old snapshot or its subscription, unless the same subscription is specified.

Overloads:

  • #delete_snapshot(request, options = nil) ⇒ ::Google::Protobuf::Empty

    Pass arguments to delete_snapshot via a request object, either of type DeleteSnapshotRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::PubSub::V1::DeleteSnapshotRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #delete_snapshot(snapshot: nil) ⇒ ::Google::Protobuf::Empty

    Pass arguments to delete_snapshot via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • snapshot (::String) (defaults to: nil) —

      Required. The name of the snapshot to delete. Format is projects/{project}/snapshots/{snap}.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

#modify_ack_deadline(request, options = nil) ⇒ ::Google::Protobuf::Empty #modify_ack_deadline(subscription: nil, ack_ids: nil, ack_deadline_seconds: nil) ⇒ ::Google::Protobuf::Empty

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.

Overloads:

  • #modify_ack_deadline(request, options = nil) ⇒ ::Google::Protobuf::Empty

    Pass arguments to modify_ack_deadline via a request object, either of type ModifyAckDeadlineRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::PubSub::V1::ModifyAckDeadlineRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #modify_ack_deadline(subscription: nil, ack_ids: nil, ack_deadline_seconds: nil) ⇒ ::Google::Protobuf::Empty

    Pass arguments to modify_ack_deadline via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • subscription (::String) (defaults to: nil) —

      Required. The name of the subscription. Format is projects/{project}/subscriptions/{sub}.

    • ack_ids (::Array<::String>) (defaults to: nil) —

      Required. List of acknowledgment IDs.

    • ack_deadline_seconds (::Integer) (defaults to: nil) —

      Required. The new ack deadline with respect to the time this request was sent to the Pub/Sub system. For example, if the value is 10, the new ack deadline will expire 10 seconds after the ModifyAckDeadline call was made. Specifying zero might immediately make the message available for delivery to another subscriber client. 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 is 600 seconds (10 minutes).

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

#modify_push_config(request, options = nil) ⇒ ::Google::Protobuf::Empty #modify_push_config(subscription: nil, push_config: nil) ⇒ ::Google::Protobuf::Empty

Modifies the PushConfig for a specified subscription.

This may be used to change a push subscription to a pull one (signified by an empty PushConfig) or vice versa, or change the endpoint URL and other attributes of a push subscription. Messages will accumulate for delivery continuously through the call regardless of changes to the PushConfig.

Overloads:

  • #modify_push_config(request, options = nil) ⇒ ::Google::Protobuf::Empty

    Pass arguments to modify_push_config via a request object, either of type ModifyPushConfigRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::PubSub::V1::ModifyPushConfigRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #modify_push_config(subscription: nil, push_config: nil) ⇒ ::Google::Protobuf::Empty

    Pass arguments to modify_push_config via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • subscription (::String) (defaults to: nil) —

      Required. The name of the subscription. Format is projects/{project}/subscriptions/{sub}.

    • push_config (::Google::Cloud::PubSub::V1::PushConfig, ::Hash) (defaults to: nil) —

      Required. The push configuration for future deliveries.

      An empty pushConfig indicates that the Pub/Sub system should stop pushing messages from the given subscription and allow messages to be pulled and acknowledged - effectively pausing the subscription if Pull or StreamingPull is not called.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

#pull(request, options = nil) ⇒ ::Google::Cloud::PubSub::V1::PullResponse #pull(subscription: nil, return_immediately: nil, max_messages: nil) ⇒ ::Google::Cloud::PubSub::V1::PullResponse

Pulls messages from the server. The server may return UNAVAILABLE if there are too many concurrent pull requests pending for the given subscription.

Overloads:

  • #pull(request, options = nil) ⇒ ::Google::Cloud::PubSub::V1::PullResponse

    Pass arguments to pull via a request object, either of type PullRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::PubSub::V1::PullRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #pull(subscription: nil, return_immediately: nil, max_messages: nil) ⇒ ::Google::Cloud::PubSub::V1::PullResponse

    Pass arguments to pull via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • subscription (::String) (defaults to: nil) —

      Required. The subscription from which messages should be pulled. Format is projects/{project}/subscriptions/{sub}.

    • return_immediately (::Boolean) (defaults to: nil) —

      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.

    • max_messages (::Integer) (defaults to: nil) —

      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.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

#seek(request, options = nil) ⇒ ::Google::Cloud::PubSub::V1::SeekResponse #seek(subscription: nil, time: nil, snapshot: nil) ⇒ ::Google::Cloud::PubSub::V1::SeekResponse

Seeks an existing subscription to a point in time or to a given snapshot, whichever is provided in the request. 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. Note that both the subscription and the snapshot must be on the same topic.

Overloads:

  • #seek(request, options = nil) ⇒ ::Google::Cloud::PubSub::V1::SeekResponse

    Pass arguments to seek via a request object, either of type Google::Cloud::PubSub::V1::SeekRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::PubSub::V1::SeekRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #seek(subscription: nil, time: nil, snapshot: nil) ⇒ ::Google::Cloud::PubSub::V1::SeekResponse

    Pass arguments to seek via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • subscription (::String) (defaults to: nil) —

      Required. The subscription to affect.

    • time (::Google::Protobuf::Timestamp, ::Hash) (defaults to: nil) —

      The time to seek to. Messages retained in the subscription that were published before this time are marked as acknowledged, and messages retained in the subscription that were published after this time are marked as unacknowledged. Note that this operation affects only those messages retained in the subscription (configured by the combination of message_retention_duration and retain_acked_messages). For example, if time corresponds to a point before the message retention window (or to a point before the system's notion of the subscription creation time), only retained messages will be marked as unacknowledged, and already-expunged messages will not be restored.

    • snapshot (::String) (defaults to: nil) —

      The snapshot to seek to. The snapshot's topic must be the same as that of the provided subscription. Format is projects/{project}/snapshots/{snap}.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

#streaming_pull(request, options = nil) {|response, operation| ... } ⇒ ::Enumerable<::Google::Cloud::PubSub::V1::StreamingPullResponse>

Establishes a stream with the server, which sends messages down to the client. The client streams acknowledgements and ack deadline modifications back to the server. 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:

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

#update_snapshot(request, options = nil) ⇒ ::Google::Cloud::PubSub::V1::Snapshot #update_snapshot(snapshot: nil, update_mask: nil) ⇒ ::Google::Cloud::PubSub::V1::Snapshot

Updates an existing snapshot. 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.

Overloads:

  • #update_snapshot(request, options = nil) ⇒ ::Google::Cloud::PubSub::V1::Snapshot

    Pass arguments to update_snapshot via a request object, either of type UpdateSnapshotRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::PubSub::V1::UpdateSnapshotRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #update_snapshot(snapshot: nil, update_mask: nil) ⇒ ::Google::Cloud::PubSub::V1::Snapshot

    Pass arguments to update_snapshot via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.
