This system provides a +// reliable many-to-many communication mechanism between independently written +// publishers and subscribers where the publisher publishes messages to "topics" +// and each subscriber creates a "subscription" and consumes messages from it. +// +// (a) The pubsub system maintains bindings between topics and subscriptions. +// (b) A publisher publishes messages into a topic. +// (c) The pubsub system delivers messages from topics into relevant +// subscriptions. +// (d) A subscriber receives pending messages from its subscription and +// acknowledges or nacks each one to the pubsub system. +// (e) The pubsub system removes acknowledged messages from that subscription. + +// ----------------------------------------------------------------------------- +// Data Model +// ----------------------------------------------------------------------------- + +// The data model consists of the following: +// +// * Topic: A topic is a resource to which messages are published by publishers. +// Topics are named, and the name of the topic is unique within the pubsub +// system. +// +// * Subscription: A subscription records the subscriber's interest in a topic. +// It can optionally include a query to select a subset of interesting +// messages. The pubsub system maintains a logical cursor tracking the +// matching messages which still need to be delivered and acked so that +// they can retried as needed. The set of messages that have not been +// acknowledged is called the subscription backlog. +// +// * Message: A message is a unit of data that flows in the system. It contains +// opaque data from the publisher along with its labels. +// +// * Message Labels (optional): A set of opaque key, value pairs assigned +// by the publisher which the subscriber can use for filtering out messages +// in the topic. For example, a label with key "foo.com/device_type" and +// value "mobile" may be added for messages that are only relevant for a +// mobile subscriber; a subscriber on a phone may decide to create a +// subscription only for messages that have this label. + +// ----------------------------------------------------------------------------- +// Publisher Flow +// ----------------------------------------------------------------------------- + +// A publisher publishes messages to the topic using the Publish request: +// +// PubsubMessage message; +// message.set_data("...."); +// Label label; +// label.set_key("foo.com/key1"); +// label.set_str_value("value1"); +// message.add_label(label); +// PublishRequest request; +// request.set_topic("topicName"); +// request.set_message(message); +// PublisherService.Publish(request); + +// ----------------------------------------------------------------------------- +// Subscriber Flow +// ----------------------------------------------------------------------------- + +// The subscriber part of the API is richer than the publisher part and has a +// number of concepts w.r.t. subscription creation and monitoring: +// +// (1) A subscriber creates a subscription using the CreateSubscription call. +// It may specify an optional "query" to indicate that it wants to receive +// only messages with a certain set of labels using the label query syntax. +// It may also specify an optional truncation policy to indicate when old +// messages from the subcription can be removed. +// +// (2) A subscriber receives messages in one of two ways: via push or pull. +// +// (a) To receive messages via push, the PushConfig field must be specified in +// the Subscription parameter when creating a subscription. The PushConfig +// specifies an endpoint at which the subscriber must expose the +// PushEndpointService. Messages are received via the HandlePubsubEvent +// method. The push subscriber responds to the HandlePubsubEvent method +// with a result code that indicates one of three things: Ack (the message +// has been successfully processed and the Pubsub system may delete it), +// Nack (the message has been rejected, the Pubsub system should resend it +// at a later time), or Push-Back (this is a Nack with the additional +// semantics that the subscriber is overloaded and the pubsub system should +// back off on the rate at which it is invoking HandlePubsubEvent). The +// endpoint may be a load balancer for better scalability. +// +// (b) To receive messages via pull a subscriber calls the Pull method on the +// SubscriberService to get messages from the subscription. For each +// individual message, the subscriber may use the ack_id received in the +// PullResponse to Ack the message, Nack the message, or modify the ack +// deadline with ModifyAckDeadline. See the +// Subscription.ack_deadline_seconds field documentation for details on the +// ack deadline behavior. +// +// Note: Messages may be consumed in parallel by multiple subscribers making +// Pull calls to the same subscription; this will result in the set of +// messages from the subscription being shared and each subscriber +// receiving a subset of the messages. +// +// (4) The subscriber can explicitly truncate the current subscription. +// +// (5) "Truncated" events are delivered when a subscription is +// truncated, whether due to the subscription's truncation policy +// or an explicit request from the subscriber. +// +// Subscription creation: +// +// Subscription subscription; +// subscription.set_topic("topicName"); +// subscription.set_name("subscriptionName"); +// subscription.push_config().set_push_endpoint("machinename:8888"); +// SubscriberService.CreateSubscription(subscription); +// +// Consuming messages via push: +// +// TODO(eschapira): Add HTTP push example. +// +// The port 'machinename:8888' must be bound to a stubby server that implements +// the PushEndpointService with the following method: +// +// int HandlePubsubEvent(PubsubEvent event) { +// if (event.subscription().equals("subscriptionName")) { +// if (event.has_message()) { +// Process(event.message().data()); +// } else if (event.truncated()) { +// ProcessTruncatedEvent(); +// } +// } +// return OK; // This return code implies an acknowledgment +// } +// +// Consuming messages via pull: +// +// The subscription must be created without setting the push_config field. +// +// PullRequest pull_request; +// pull_request.set_subscription("subscriptionName"); +// pull_request.set_return_immediately(false); +// while (true) { +// PullResponse pull_response; +// if (SubscriberService.Pull(pull_request, pull_response) == OK) { +// PubsubEvent event = pull_response.pubsub_event(); +// if (event.has_message()) { +// Process(event.message().data()); +// } else if (event.truncated()) { +// ProcessTruncatedEvent(); +// } +// AcknowledgeRequest ack_request; +// ackRequest.set_subscription("subscriptionName"); +// ackRequest.set_ack_id(pull_response.ack_id()); +// SubscriberService.Acknowledge(ack_request); +// } +// } + +// ----------------------------------------------------------------------------- +// Reliability Semantics +// ----------------------------------------------------------------------------- + +// When a subscriber successfully creates a subscription using +// Subscriber.CreateSubscription, it establishes a "subscription point" with +// respect to that subscription - the subscriber is guaranteed to receive any +// message published after this subscription point that matches the +// subscription's query. Note that messages published before the Subscription +// point may or may not be delivered. +// +// If the system truncates the subscription according to the specified +// truncation policy, the system delivers a subscription status event with the +// "truncated" field set to true. We refer to such events as "truncation +// events". A truncation event: +// +// * Informs the subscriber that part of the subscription messages have been +// discarded. The subscriber may want to recover from the message loss, e.g., +// by resyncing its state with its backend. +// * Establishes a new subscription point, i.e., the subscriber is guaranteed to +// receive all changes published after the trunction event is received (or +// until another truncation event is received). +// +// Note that messages are not delivered in any particular order by the pubsub +// system. Furthermore, the system guarantees at-least-once delivery +// of each message or truncation events until acked. + +// ----------------------------------------------------------------------------- +// Deletion +// ----------------------------------------------------------------------------- + +// Both topics and subscriptions may be deleted. Deletion of a topic implies +// deletion of all attached subscriptions. +// +// When a subscription is deleted directly by calling DeleteSubscription, all +// messages are immediately dropped.

This system provides a -// reliable many-to-many communication mechanism between independently written -// publishers and subscribers where the publisher publishes messages to "topics" -// and each subscriber creates a "subscription" and consumes messages from it. -// -// (a) The pubsub system maintains bindings between topics and subscriptions. -// (b) A publisher publishes messages into a topic. -// (c) The pubsub system delivers messages from topics into relevant -// subscriptions. -// (d) A subscriber receives pending messages from its subscription and -// acknowledges or nacks each one to the pubsub system. -// (e) The pubsub system removes acknowledged messages from that subscription. - -// ----------------------------------------------------------------------------- -// Data Model -// ----------------------------------------------------------------------------- - -// The data model consists of the following: -// -// * Topic: A topic is a resource to which messages are published by publishers. -// Topics are named, and the name of the topic is unique within the pubsub -// system. -// -// * Subscription: A subscription records the subscriber's interest in a topic. -// It can optionally include a query to select a subset of interesting -// messages. The pubsub system maintains a logical cursor tracking the -// matching messages which still need to be delivered and acked so that -// they can retried as needed. The set of messages that have not been -// acknowledged is called the subscription backlog. -// -// * Message: A message is a unit of data that flows in the system. It contains -// opaque data from the publisher along with its labels. -// -// * Message Labels (optional): A set of opaque key, value pairs assigned -// by the publisher which the subscriber can use for filtering out messages -// in the topic. For example, a label with key "foo.com/device_type" and -// value "mobile" may be added for messages that are only relevant for a -// mobile subscriber; a subscriber on a phone may decide to create a -// subscription only for messages that have this label. - -// ----------------------------------------------------------------------------- -// Publisher Flow -// ----------------------------------------------------------------------------- - -// A publisher publishes messages to the topic using the Publish request: -// -// PubsubMessage message; -// message.set_data("...."); -// Label label; -// label.set_key("foo.com/key1"); -// label.set_str_value("value1"); -// message.add_label(label); -// PublishRequest request; -// request.set_topic("topicName"); -// request.set_message(message); -// PublisherService.Publish(request); - -// ----------------------------------------------------------------------------- -// Subscriber Flow -// ----------------------------------------------------------------------------- - -// The subscriber part of the API is richer than the publisher part and has a -// number of concepts w.r.t. subscription creation and monitoring: -// -// (1) A subscriber creates a subscription using the CreateSubscription call. -// It may specify an optional "query" to indicate that it wants to receive -// only messages with a certain set of labels using the label query syntax. -// It may also specify an optional truncation policy to indicate when old -// messages from the subcription can be removed. -// -// (2) A subscriber receives messages in one of two ways: via push or pull. -// -// (a) To receive messages via push, the PushConfig field must be specified in -// the Subscription parameter when creating a subscription. The PushConfig -// specifies an endpoint at which the subscriber must expose the -// PushEndpointService. Messages are received via the HandlePubsubEvent -// method. The push subscriber responds to the HandlePubsubEvent method -// with a result code that indicates one of three things: Ack (the message -// has been successfully processed and the Pubsub system may delete it), -// Nack (the message has been rejected, the Pubsub system should resend it -// at a later time), or Push-Back (this is a Nack with the additional -// semantics that the subscriber is overloaded and the pubsub system should -// back off on the rate at which it is invoking HandlePubsubEvent). The -// endpoint may be a load balancer for better scalability. -// -// (b) To receive messages via pull a subscriber calls the Pull method on the -// SubscriberService to get messages from the subscription. For each -// individual message, the subscriber may use the ack_id received in the -// PullResponse to Ack the message, Nack the message, or modify the ack -// deadline with ModifyAckDeadline. See the -// Subscription.ack_deadline_seconds field documentation for details on the -// ack deadline behavior. -// -// Note: Messages may be consumed in parallel by multiple subscribers making -// Pull calls to the same subscription; this will result in the set of -// messages from the subscription being shared and each subscriber -// receiving a subset of the messages. -// -// (4) The subscriber can explicitly truncate the current subscription. -// -// (5) "Truncated" events are delivered when a subscription is -// truncated, whether due to the subscription's truncation policy -// or an explicit request from the subscriber. -// -// Subscription creation: -// -// Subscription subscription; -// subscription.set_topic("topicName"); -// subscription.set_name("subscriptionName"); -// subscription.push_config().set_push_endpoint("machinename:8888"); -// SubscriberService.CreateSubscription(subscription); -// -// Consuming messages via push: -// -// TODO(eschapira): Add HTTP push example. -// -// The port 'machinename:8888' must be bound to a stubby server that implements -// the PushEndpointService with the following method: -// -// int HandlePubsubEvent(PubsubEvent event) { -// if (event.subscription().equals("subscriptionName")) { -// if (event.has_message()) { -// Process(event.message().data()); -// } else if (event.truncated()) { -// ProcessTruncatedEvent(); -// } -// } -// return OK; // This return code implies an acknowledgment -// } -// -// Consuming messages via pull: -// -// The subscription must be created without setting the push_config field. -// -// PullRequest pull_request; -// pull_request.set_subscription("subscriptionName"); -// pull_request.set_return_immediately(false); -// while (true) { -// PullResponse pull_response; -// if (SubscriberService.Pull(pull_request, pull_response) == OK) { -// PubsubEvent event = pull_response.pubsub_event(); -// if (event.has_message()) { -// Process(event.message().data()); -// } else if (event.truncated()) { -// ProcessTruncatedEvent(); -// } -// AcknowledgeRequest ack_request; -// ackRequest.set_subscription("subscriptionName"); -// ackRequest.set_ack_id(pull_response.ack_id()); -// SubscriberService.Acknowledge(ack_request); -// } -// } - -// ----------------------------------------------------------------------------- -// Reliability Semantics -// ----------------------------------------------------------------------------- - -// When a subscriber successfully creates a subscription using -// Subscriber.CreateSubscription, it establishes a "subscription point" with -// respect to that subscription - the subscriber is guaranteed to receive any -// message published after this subscription point that matches the -// subscription's query. Note that messages published before the Subscription -// point may or may not be delivered. -// -// If the system truncates the subscription according to the specified -// truncation policy, the system delivers a subscription status event with the -// "truncated" field set to true. We refer to such events as "truncation -// events". A truncation event: -// -// * Informs the subscriber that part of the subscription messages have been -// discarded. The subscriber may want to recover from the message loss, e.g., -// by resyncing its state with its backend. -// * Establishes a new subscription point, i.e., the subscriber is guaranteed to -// receive all changes published after the trunction event is received (or -// until another truncation event is received). -// -// Note that messages are not delivered in any particular order by the pubsub -// system. Furthermore, the system guarantees at-least-once delivery -// of each message or truncation events until acked. - -// ----------------------------------------------------------------------------- -// Deletion -// ----------------------------------------------------------------------------- - -// Both topics and subscriptions may be deleted. Deletion of a topic implies -// deletion of all attached subscriptions. -// -// When a subscription is deleted directly by calling DeleteSubscription, all -// messages are immediately dropped.

Add response parameters to custom_metadata streaming request for Node and PHP clients. The Java server does not respond with separate initial and trailing metadata when there is no response data - it is only emiting the requested trailing metadata.
