Class Client (2.33.0) 

Client(     subscriber_options: typing.Union[         google.cloud.pubsub_v1.types.SubscriberOptions, typing.Sequence     ] = (),     **kwargs: typing.Any )

A subscriber client for Google Cloud Pub/Sub.

This creates an object that is capable of subscribing to messages. Generally, you can instantiate this client with no arguments, and you get sensible defaults.

Properties

api

The underlying gapic API client.

.. versionchanged:: 2.10.0 Instead of a GAPIC SubscriberClient client instance, this property is a proxy object to it with the same interface.

api_endpoint

Return the API endpoint used by the client instance.

Returns
Type Description
str The API endpoint used by the client instance.

closed

Return whether the client has been closed and cannot be used anymore.

.. versionadded:: 2.8.0

open_telemetry_enabled

Returns True if Open Telemetry is enabled. False otherwise.

target

Return the target (where the API is).

transport

Returns the transport used by the client instance.

Returns
Type Description
SubscriberTransport The transport used by the client instance.

universe_domain

Return the universe domain used by the client instance.

Returns
Type Description
str The universe domain used by the client instance.

Methods

Client

Client(     subscriber_options: typing.Union[         google.cloud.pubsub_v1.types.SubscriberOptions, typing.Sequence     ] = (),     **kwargs: typing.Any )

Instantiates the subscriber client.

Parameters
Name Description
credentials Optional[google.auth.credentials.Credentials]

The authorization credentials to attach to requests. These credentials identify the application to the service; if none are specified, the client will attempt to ascertain the credentials from the environment.
transport Optional[Union[str,SubscriberTransport,Callable[..., SubscriberTransport]]]

The transport to use, or a Callable that constructs and returns a new transport. If a Callable is given, it will be called with the same set of initialization arguments as used in the SubscriberTransport constructor. If set to None, a transport is chosen automatically.
client_options Optional[Union[google.api_core.client_options.ClientOptions, dict]]

Custom options for the client. 1. The api_endpoint property can be used to override the default endpoint provided by the client when transport is not explicitly provided. Only if this property is not set and transport was not explicitly provided, the endpoint is determined by the GOOGLE_API_USE_MTLS_ENDPOINT environment variable, which have one of the following values: "always" (always use the default mTLS endpoint), "never" (always use the default regular endpoint) and "auto" (auto-switch to the default mTLS endpoint if client certificate is present; this is the default value). 2. If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "true", then the client_cert_source property can be used to provide a client certificate for mTLS transport. If not provided, the default SSL client certificate will be used if present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not set, no client certificate will be used. 3. The universe_domain property can be used to override the default "googleapis.com" universe. Note that the api_endpoint property still takes precedence; and universe_domain is currently not supported for mTLS.
client_info google.api_core.gapic_v1.client_info.ClientInfo

The client info used to send a user-agent string along with API requests. If None, then default info will be used. Generally, you only need to set this if you're developing your own client library.
Exceptions
Type Description
google.auth.exceptions.MutualTLSChannelError If mutual TLS transport creation failed for any reason.

acknowledge

acknowledge(     request: typing.Optional[         typing.Union[google.cloud.pubsub_v1.types.AcknowledgeRequest, dict]     ] = None,     *,     subscription: typing.Optional[str] = None,     ack_ids: typing.Optional[typing.MutableSequence[str]] = None,     retry: typing.Optional[         typing.Union[             google.api_core.retry.retry_unary.Retry,             google.api_core.gapic_v1.method._MethodDefault,         ]     ] = _MethodDefault._DEFAULT_VALUE,     timeout: typing.Union[float, object] = _MethodDefault._DEFAULT_VALUE,     metadata: typing.Sequence[typing.Tuple[str, typing.Union[str, bytes]]] = () ) -> None

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.

Parameters
Name Description
request Union[google.pubsub_v1.types.AcknowledgeRequest, dict]

The request object. Request for the Acknowledge method.
subscription str

Required. The subscription whose message is being acknowledged. Format is projects/{project}/subscriptions/{sub}. This corresponds to the subscription field on the request instance; if request is provided, this should not be set.
ack_ids MutableSequence[str]

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. This corresponds to the ack_ids field on the request instance; if request is provided, this should not be set.

create_snapshot

create_snapshot(     request: typing.Optional[         typing.Union[google.cloud.pubsub_v1.types.CreateSnapshotRequest, dict]     ] = None,     *,     name: typing.Optional[str] = None,     subscription: typing.Optional[str] = None,     retry: typing.Optional[         typing.Union[             google.api_core.retry.retry_unary.Retry,             google.api_core.gapic_v1.method._MethodDefault,         ]     ] = _MethodDefault._DEFAULT_VALUE,     timeout: typing.Union[float, object] = _MethodDefault._DEFAULT_VALUE,     metadata: typing.Sequence[typing.Tuple[str, typing.Union[str, bytes]]] = () ) -> google.cloud.pubsub_v1.types.Snapshot

Creates a snapshot from the requested subscription. Snapshots are used in Seek <https://cloud.google.com/pubsub/docs/replay-overview>__ 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.

Parameters
Name Description
request Union[google.pubsub_v1.types.CreateSnapshotRequest, dict]

The request object. Request for the CreateSnapshot method.
name str

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 https://cloud.google.com/pubsub/docs/pubsub-basics#resource_names__. Format is projects/{project}/snapshots/{snap}. This corresponds to the name field on the request instance; if request is provided, this should not be set.
subscription str

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}. This corresponds to the subscription field on the request instance; if request is provided, this should not be set.
retry google.api_core.retry.Retry

Designation of what errors, if any, should be retried.
timeout float

The timeout for this request.
metadata Sequence[Tuple[str, Union[str, bytes]]]

Key/value pairs which should be sent along with the request as metadata. Normally, each value must be of type str, but for metadata keys ending with the suffix -bin, the corresponding values must be of type bytes.
Returns
Type Description
google.pubsub_v1.types.Snapshot A snapshot resource. Snapshots are used in [Seek](https://cloud.google.com/pubsub/docs/replay-overview) 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.

create_subscription

create_subscription(     request: typing.Optional[         typing.Union[google.cloud.pubsub_v1.types.Subscription, dict]     ] = None,     *,     name: typing.Optional[str] = None,     topic: typing.Optional[str] = None,     push_config: typing.Optional[google.cloud.pubsub_v1.types.PushConfig] = None,     ack_deadline_seconds: typing.Optional[int] = None,     retry: typing.Optional[         typing.Union[             google.api_core.retry.retry_unary.Retry,             google.api_core.gapic_v1.method._MethodDefault,         ]     ] = _MethodDefault._DEFAULT_VALUE,     timeout: typing.Union[float, object] = _MethodDefault._DEFAULT_VALUE,     metadata: typing.Sequence[typing.Tuple[str, typing.Union[str, bytes]]] = () ) -> google.cloud.pubsub_v1.types.Subscription

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
request Union[google.pubsub_v1.types.Subscription, dict]

The request object. A subscription resource. If none of push_config, bigquery_config, or cloud_storage_config is set, then the subscriber will pull and ack messages using API methods. At most one of these fields may be set.
name str

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 (<code>+</code><code>) or percent signs (</code><code>%</code><code>). It must be between 3 and 255 characters in length, and it must not start with </code>"goog"<code>. This corresponds to the </code>name<code> field on the </code>request<code> instance; if </code>request is provided, this should not be set.
                     		       
       
         topic                    str           
           
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. This corresponds to the topic field on the request instance; if request is provided, this should not be set.
                     		       
       
         push_config                    google.pubsub_v1.types.PushConfig           
           
Optional. If push delivery is used with this subscription, this field is used to configure it. This corresponds to the push_config field on the request instance; if request is provided, this should not be set.
                     		       
       
         ack_deadline_seconds                    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. This corresponds to the ack_deadline_seconds field on the request instance; if request is provided, this should not be set.
                     		       
       
         retry                    google.api_core.retry.Retry           
           
Designation of what errors, if any, should be retried.
                     		       
       
         timeout                    float           
           
The timeout for this request.
                     		       
       
         metadata                    Sequence[Tuple[str, Union[str, bytes]]]           
           
Key/value pairs which should be sent along with the request as metadata. Normally, each value must be of type str, but for metadata keys ending with the suffix -bin, the corresponding values must be of type bytes.
                     		       
        
   
            
         Returns       
       
         Type         Description       
       
         google.pubsub_v1.types.Subscription         A subscription resource. If none of push_config, bigquery_config, or cloud_storage_config is set, then the subscriber will pull and ack messages using API methods. At most one of these fields may be set.       
        
   
delete_snapshot
   
     
delete_snapshot(     request: typing.Optional[         typing.Union[google.cloud.pubsub_v1.types.DeleteSnapshotRequest, dict]     ] = None,     *,     snapshot: typing.Optional[str] = None,     retry: typing.Optional[         typing.Union[             google.api_core.retry.retry_unary.Retry,             google.api_core.gapic_v1.method._MethodDefault,         ]     ] = _MethodDefault._DEFAULT_VALUE,     timeout: typing.Union[float, object] = _MethodDefault._DEFAULT_VALUE,     metadata: typing.Sequence[typing.Tuple[str, typing.Union[str, bytes]]] = () ) -> None
   
   
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.

         .policy_pb2.Policy         Defines an Identity and Access Management (IAM) policy. It is used to specify access control policies for Cloud Platform resources. A Policy is a collection of bindings. A binding binds one or more members to a single role. Members can be user accounts, service accounts, Google groups, and domains (such as G Suite). A role is a named list of permissions (defined by IAM or configured by users). A binding can optionally specify a condition, which is a logic expression that further constrains the role binding based on attributes about the request and/or target resource. **JSON Example** :: { "bindings": [ { "role": "roles/resourcemanager.organizationAdmin", "members": [ "user:[email protected]", "group:[email protected]", "domain:google.com", "serviceAccount:[email protected]" ] }, { "role": "roles/resourcemanager.organizationViewer", "members": ["user:[email protected]"], "condition": { "title": "expirable access", "description": "Does not grant access after Sep 2020", "expression": "request.time < timestamp('2020-10-01t00:00:00.000z')",="" }="" }="" ]="" }="" **yaml="" example**="" ::="" bindings:="" -="" members:="" -="" user:[email protected]="" -="" group:[email protected]="" -="" domain:google.com="" -="" serviceaccount:[email protected]="" role:="" roles/resourcemanager.organizationadmin="" -="" members:="" -="" user:[email protected]="" role:="" roles/resourcemanager.organizationviewer="" condition:="" title:="" expirable="" access="" description:="" does="" not="" grant="" access="" after="" sep="" 2020="" expression:="" request.time="">< timestamp('2020-10-01t00:00:00.000z')="" for="" a="" description="" of="" iam="" and="" its="" features,="" see="" the="">IAM developer's guide __.

Deprecated. Return the API endpoint and client cert source for mutual TLS.
 
The client cert source is determined in the following order: (1) if GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is not "true", the client cert source is None. (2) if client_options.client_cert_source is provided, use the provided one; if the default client cert source exists, use the default one; otherwise the client cert source is None.
 
The API endpoint is determined in the following order: (1) if client_options.api_endpoint if provided, use the provided one. (2) if GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "always", use the default mTLS endpoint; if the environment variable is "never", use the default API endpoint; otherwise if client cert source exists, use the default mTLS endpoint, otherwise use the default API endpoint.

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                    Union[google.pubsub_v1.types.ModifyAckDeadlineRequest, dict]           
           
The request object. Request for the ModifyAckDeadline method.
                     		       
       
         subscription                    str           
           
Required. The name of the subscription. Format is projects/{project}/subscriptions/{sub}. This corresponds to the subscription field on the request instance; if request is provided, this should not be set.
                     		       
       
         ack_ids                    MutableSequence[str]           
           
Required. List of acknowledgment IDs. This corresponds to the ack_ids field on the request instance; if request is provided, this should not be set.
                     		       
       
         ack_deadline_seconds                    int           
           
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 in a single request is 600 seconds (10 minutes). This corresponds to the ack_deadline_seconds field on the request instance; if request is provided, this should not be set.

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.

         .policy_pb2.Policy         Defines an Identity and Access Management (IAM) policy. It is used to specify access control policies for Cloud Platform resources. A Policy is a collection of bindings. A binding binds one or more members to a single role. Members can be user accounts, service accounts, Google groups, and domains (such as G Suite). A role is a named list of permissions (defined by IAM or configured by users). A binding can optionally specify a condition, which is a logic expression that further constrains the role binding based on attributes about the request and/or target resource. **JSON Example** :: { "bindings": [ { "role": "roles/resourcemanager.organizationAdmin", "members": [ "user:[email protected]", "group:[email protected]", "domain:google.com", "serviceAccount:[email protected]" ] }, { "role": "roles/resourcemanager.organizationViewer", "members": ["user:[email protected]"], "condition": { "title": "expirable access", "description": "Does not grant access after Sep 2020", "expression": "request.time < timestamp('2020-10-01t00:00:00.000z')",="" }="" }="" ]="" }="" **yaml="" example**="" ::="" bindings:="" -="" members:="" -="" user:[email protected]="" -="" group:[email protected]="" -="" domain:google.com="" -="" serviceaccount:[email protected]="" role:="" roles/resourcemanager.organizationadmin="" -="" members:="" -="" user:[email protected]="" role:="" roles/resourcemanager.organizationviewer="" condition:="" title:="" expirable="" access="" description:="" does="" not="" grant="" access="" after="" sep="" 2020="" expression:="" request.time="">< timestamp('2020-10-01t00:00:00.000z')="" for="" a="" description="" of="" iam="" and="" its="" features,="" see="" the="">IAM developer's guide __.

Establishes a stream with the server, which sends messages down to the client. The client streams acknowledgments 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.

         Returns       
       
         Type         Description       
       
         Iterable[google.pubsub_v1.types.StreamingPullResponse]         Response for the StreamingPull method. This response is used to stream messages from the server to the client.       
        
   
subscribe
   
     
subscribe(     subscription: str,     callback: typing.Callable[[subscriber.message.Message], typing.Any],     flow_control: typing.Union[         google.cloud.pubsub_v1.types.FlowControl, typing.Sequence     ] = (),     scheduler: typing.Optional[subscriber.scheduler.ThreadScheduler] = None,     use_legacy_flow_control: bool = False,     await_callbacks_on_shutdown: bool = False, ) -> google.cloud.pubsub_v1.subscriber.futures.StreamingPullFuture
   
   
Asynchronously start receiving messages on a given subscription.
 
This method starts a background thread to begin pulling messages from a Pub/Sub subscription and scheduling them to be processed using the provided callback.
 
The callback will be called with an individual xref_Message. It is the responsibility of the callback to either call ack() or nack() on the message when it finished processing. If an exception occurs in the callback during processing, the exception is logged and the message is nack() ed.
 
The flow_control argument can be used to control the rate of at which messages are pulled. The settings are relatively conservative by default to prevent "message hoarding" - a situation where the client pulls a large number of messages but can not process them fast enough leading it to "starve" other clients of messages. Increasing these settings may lead to faster throughput for messages that do not take a long time to process.
 
The use_legacy_flow_control argument disables enforcing flow control settings at the Cloud Pub/Sub server, and only the client side flow control will be enforced.
 
This method starts the receiver in the background and returns a Future representing its execution. Waiting on the future (calling result()) will block forever or until a non-recoverable error is encountered (such as loss of network connectivity). Cancelling the future will signal the process to shutdown gracefully and exit.
 
 Example:
 
from google.cloud import pubsub_v1  subscriber_client = pubsub_v1.SubscriberClient()  # existing subscription subscription = subscriber_client.subscription_path(     'my-project-id', 'my-subscription')  def callback(message):     print(message)     message.ack()  future = subscriber_client.subscribe(     subscription, callback)  try:     future.result() except KeyboardInterrupt:     future.cancel()  # Trigger the shutdown.     future.result()  # Block until the shutdown is complete. 
   
            
         Parameter       
       
         Name         Description       
       
         use_legacy_flow_control                    bool           
           
If set to True, flow control at the Cloud Pub/Sub server is disabled, though client-side flow control is still enabled. If set to False (default), both server-side and client-side flow control are enabled.
