+# Google Cloud Pub/Sub Bindings
+
+This document defines how to describe Google Cloud Pub/Sub specific information with AsyncAPI.
+
+
+
+## Version
+
+Current version is `0.1.0`.
+
+
+
+## Channel Binding Object
+
+The `Channel Bindings Object` is used to describe the Google Cloud Pub/Sub specific
+[Topic](https://cloud.google.com/pubsub/docs/reference/rest/v1/projects.topics/create) details with AsyncAPI.
+
+Field Name | Type | Description
+---|---|---
+`bindingVersion`|String|The current version is `0.1.0`
+`labels`|Object|An object of key-value pairs _(These are used to categorize Cloud Resources like Cloud Pub/Sub Topics.)_
+`messageRetentionDuration`|String|Indicates the minimum duration to retain a message after it is published to the topic _(Must be a valid [Duration](https://developers.google.com/protocol-buffers/docs/reference/google.protobuf#google.protobuf.Duration).)_
+`messageStoragePolicy`|[Message Storage Policy Object](#message-storage-policy-object)|Policy constraining the set of Google Cloud Platform regions where messages published to the topic may be stored
+`schemaSettings`|[Schema Settings Object](#schema-settings-object)|Settings for validating messages published against a schema
+`topic`|String|The Google Cloud Pub/Sub Topic name
+
+
+
+### Message Storage Policy Object
+
+The `Message Storage Policy Object` is used to describe the Google Cloud Pub/Sub
+[MessageStoragePolicy](https://cloud.google.com/pubsub/docs/reference/rest/v1/projects.topics#MessageStoragePolicy)
+Object with AsyncAPI.
+
+Field Name | Type | Description
+---|---|---
+`allowedPersistenceRegions`|String[]|A list of IDs of GCP regions where messages that are published to the topic may be persisted in storage
+
+
+
+### Schema Settings Object
+
+The `Schema Settings Object` is used to describe the Google Cloud Pub/Sub
+[SchemaSettings](https://cloud.google.com/pubsub/docs/reference/rest/v1/projects.topics#SchemaSettings) Object with
+AsyncAPI.
+
+Field Name | Type | Description
+---|---|---
+`encoding`|String|The encoding of the message _(Must be one of the possible [Encoding](https://cloud.google.com/pubsub/docs/reference/rest/v1/projects.topics#encoding) values.)_
+`firstRevisionId`|String|The minimum _(inclusive)_ revision allowed for validating messages
+`lastRevisionId`|String|The maximum _(inclusive)_ revision allowed for validating messages
+`name`|String|The name of the schema that messages published should be validated against _(The format is `projects/{project}/schemas/{schema}`.)_
+
+
+
+### Example
+
+```yaml
+# ...
+channels:
+ topic-avro-schema:
+ bindings:
+ googlepubsub:
+ topic: projects/your-project/topics/topic-avro-schema
+ schemaSettings:
+ encoding: json
+ name: projects/your-project/schemas/message-avro
+# ...
+ topic-proto-schema:
+ bindings:
+ googlepubsub:
+ topic: projects/your-project/topics/topic-proto-schema
+ messageRetentionDuration: 86400s
+ messageStoragePolicy:
+ allowedPersistenceRegions:
+ - us-central1
+ - us-central2
+ - us-east1
+ - us-east4
+ - us-east5
+ - us-east7
+ - us-south1
+ - us-west1
+ - us-west2
+ - us-west3
+ - us-west4
+ schemaSettings:
+ encoding: binary
+ name: projects/your-project/schemas/message-proto
+# ...
+```
+
+
+
+## Message Binding Object
+
+The `Message Binding Object` is used to describe the Google Cloud Pub/Sub specific
+[PubsubMessage](https://cloud.google.com/pubsub/docs/reference/rest/v1/PubsubMessage) details, alongside with pertintent
+parts of the Google Cloud Pub/Sub
+[Schema](https://cloud.google.com/pubsub/docs/reference/rest/v1/projects.schemas#Schema)
+Object, with AsyncAPI.
+
+Field Name | Type | Description
+---|---|---
+`bindingVersion`|String|The current version is `0.1.0`
+`attributes`|Object|Attributes for this message _(If this field is empty, the message must contain non-empty data. This can be used to filter messages on the subscription.)_
+`orderingKey`|String|If non-empty, identifies related messages for which publish order should be respected _(For more information, see [ordering messages](https://cloud.google.com/pubsub/docs/ordering).)_
+`schema`|[Schema Definition Object](#schema-definition-object)|Describes the schema used to validate the payload of this message
+
+
+
+### Schema Definition Object
+
+The `Schema Definition Object` is used to describe the Google Cloud Pub/Sub
+[Schema]([Schema](https://cloud.google.com/pubsub/docs/reference/rest/v1/projects.schemas#Schema)) Object with AsyncAPI.
+While some of this information could be, or is, described using native AsyncAPI, for consistency it makes sense to
+provide this information here at all times, especially for cases where AsyncAPI does not natively support describing
+payloads using a supported Google Cloud Pub/Sub schema format like Protobuf.
+
+Field Name | Type | Description
+---|---|---
+`name`|String|The name of the schema
+`type`|String|The type of the schema
+
+
+
+### Example
+
+```yaml
+# ...
+components:
+ messages:
+ messageAvroAsJSON:
+ bindings:
+ googlepubsub:
+ schema:
+ name: projects/your-project/schemas/message-avro
+ type: avro
+ contentType: application/json
+ name: projects/your-project/schemas/message-avro
+ payload:
+ fields:
+ - name: message
+ type: string
+ name: Message
+ type: record
+ schemaFormat: application/vnd.apache.avro+yaml;version=1.9.0
+ messageProto:
+ bindings:
+ googlepubsub:
+ schema:
+ name: projects/your-project/schemas/message-proto
+ type: protobuf
+ contentType: application/octet-stream
+ name: projects/your-project/schemas/message-proto
+ payload: true
+# ...
+```
+
+
+
+## Operation Binding Object
+
+This object MUST NOT contain any properties. Its name is reserved for future use.
+
+
+
+## Server Binding Object
+
+This object MUST NOT contain any properties. Its name is reserved for future use.
