Instance Method Details

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

Configure the Publisher 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.

Yield Parameters:

Returns:

Creates the given topic with the given name. See the resource name rules.

Examples:

Basic example

require "google/cloud/pubsub/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::PubSub::V1::Publisher::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::PubSub::V1::Topic.new

# Call the create_topic method.
result = client.create_topic request

# The returned object is of type Google::Cloud::PubSub::V1::Topic.
p result

Overloads:

  • #create_topic(request, options = nil) ⇒ ::Google::Cloud::PubSub::V1::Topic

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

    Parameters:

    • request (::Google::Cloud::PubSub::V1::Topic, ::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_topic(name: nil, labels: nil, message_storage_policy: nil, kms_key_name: nil, schema_settings: nil, satisfies_pzs: nil, message_retention_duration: nil, ingestion_data_source_settings: nil) ⇒ ::Google::Cloud::PubSub::V1::Topic

    Pass arguments to create_topic 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 topic. It must have the format "projects/{project}/topics/{topic}". {topic} 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".

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

      Optional. See Creating and managing labels.

    • message_storage_policy (::Google::Cloud::PubSub::V1::MessageStoragePolicy, ::Hash) (defaults to: nil) —

      Optional. Policy constraining the set of Google Cloud Platform regions where messages published to the topic may be stored. If not present, then no constraints are in effect.

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

      Optional. The resource name of the Cloud KMS CryptoKey to be used to protect access to messages published on this topic.

      The expected format is projects/*/locations/*/keyRings/*/cryptoKeys/*.

    • schema_settings (::Google::Cloud::PubSub::V1::SchemaSettings, ::Hash) (defaults to: nil) —

      Optional. Settings for validating messages published against a schema.

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

      Optional. Reserved for future use. This field is set only in responses from the server; it is ignored if it is set in any requests.

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

      Optional. Indicates the minimum duration to retain a message after it is published to the topic. If this field is set, messages published to the topic in the last message_retention_duration are always available to subscribers. For instance, it allows any attached subscription to seek to a timestamp that is up to message_retention_duration in the past. If this field is not set, message retention is controlled by settings on individual subscriptions. Cannot be more than 31 days or less than 10 minutes.

    • ingestion_data_source_settings (::Google::Cloud::PubSub::V1::IngestionDataSourceSettings, ::Hash) (defaults to: nil) —

      Optional. Settings for ingestion from a data source into this topic.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

#delete_topic(request, options = nil) ⇒ ::Google::Protobuf::Empty #delete_topic(topic: nil) ⇒ ::Google::Protobuf::Empty

Deletes the topic with the given name. Returns NOT_FOUND if the topic does not exist. After a topic is deleted, a new topic may be created with the same name; this is an entirely new topic with none of the old configuration or subscriptions. Existing subscriptions to this topic are not deleted, but their topic field is set to _deleted-topic_.

Examples:

Basic example

require "google/cloud/pubsub/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::PubSub::V1::Publisher::Client.new

# Create a request. To set request fields, pass in keyword arguments.

#detach_subscription(request, options = nil) ⇒ ::Google::Cloud::PubSub::V1::DetachSubscriptionResponse #detach_subscription(subscription: nil) ⇒ ::Google::Cloud::PubSub::V1::DetachSubscriptionResponse

Detaches a subscription from this topic. All messages retained in the subscription are dropped. Subsequent Pull and StreamingPull requests will return FAILED_PRECONDITION. If the subscription is a push subscription, pushes to the endpoint will stop.

Examples:

Basic example

require "google/cloud/pubsub/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::PubSub::V1::Publisher::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::PubSub::V1::DetachSubscriptionRequest.new

# Call the detach_subscription method.
result = client.detach_subscription request

# The returned object is of type Google::Cloud::PubSub::V1::DetachSubscriptionResponse.
p result

Overloads:

  • #detach_subscription(request, options = nil) ⇒ ::Google::Cloud::PubSub::V1::DetachSubscriptionResponse

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

    Parameters:

    • request (::Google::Cloud::PubSub::V1::DetachSubscriptionRequest, ::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.

  • #detach_subscription(subscription: nil) ⇒ ::Google::Cloud::PubSub::V1::DetachSubscriptionResponse

    Pass arguments to detach_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:

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

      Required. The subscription to detach. Format is projects/{project}/subscriptions/{subscription}.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

#publish(request, options = nil) ⇒ ::Google::Cloud::PubSub::V1::PublishResponse #publish(topic: nil, messages: nil) ⇒ ::Google::Cloud::PubSub::V1::PublishResponse

Adds one or more messages to the topic. Returns NOT_FOUND if the topic does not exist.

Examples:

Basic example

require "google/cloud/pubsub/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::PubSub::V1::Publisher::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::PubSub::V1::PublishRequest.new

# Call the publish method.
result = client.publish request

# The returned object is of type Google::Cloud::PubSub::V1::PublishResponse.
p result

Overloads:

  • #publish(request, options = nil) ⇒ ::Google::Cloud::PubSub::V1::PublishResponse

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

    Parameters:

    • request (::Google::Cloud::PubSub::V1::PublishRequest, ::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.

  • #publish(topic: nil, messages: nil) ⇒ ::Google::Cloud::PubSub::V1::PublishResponse

    Pass arguments to publish 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:

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

      Required. The messages in the request will be published on this topic. Format is projects/{project}/topics/{topic}.

    • messages (::Array<::Google::Cloud::PubSub::V1::PubsubMessage, ::Hash>) (defaults to: nil) —

      Required. The messages to publish.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

#update_topic(request, options = nil) ⇒ ::Google::Cloud::PubSub::V1::Topic #update_topic(topic: nil, update_mask: nil) ⇒ ::Google::Cloud::PubSub::V1::Topic

Updates an existing topic by updating the fields specified in the update mask. Note that certain properties of a topic are not modifiable.

Examples:

Basic example

require "google/cloud/pubsub/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::PubSub::V1::Publisher::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::PubSub::V1::UpdateTopicRequest.new

# Call the update_topic method.
result = client.update_topic request

# The returned object is of type Google::Cloud::PubSub::V1::Topic.
p result

Overloads:

  • #update_topic(request, options = nil) ⇒ ::Google::Cloud::PubSub::V1::Topic

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

    Parameters:

    • request (::Google::Cloud::PubSub::V1::UpdateTopicRequest, ::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_topic(topic: nil, update_mask: nil) ⇒ ::Google::Cloud::PubSub::V1::Topic

    Pass arguments to update_topic 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:

    • topic (::Google::Cloud::PubSub::V1::Topic, ::Hash) (defaults to: nil) —

      Required. The updated topic object.

    • update_mask (::Google::Protobuf::FieldMask, ::Hash) (defaults to: nil) —

      Required. Indicates which fields in the provided topic to update. Must be specified and non-empty. Note that if update_mask contains "message_storage_policy" but the message_storage_policy is not set in the topic provided above, then the updated value is determined by the policy configured at the project or organization level.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.
