PubsubMessage (message)

PubsubMessage

A message that is published by publishers and consumed by subscribers. The message must contain either a non-empty data field or at least one attribute. Note that client libraries represent this object differently depending on the language. See the corresponding client library documentation for more information. See quotas and limits for more information about message limits.

Fields
`data`	`bytes` The message data field. If this field is empty, the message must contain at least one attribute.
`attributes`	`map<string, string>` 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.
`message_id`	`string` ID of this message, assigned by the server when the message is published. Guaranteed to be unique within the topic. This value may be read by a subscriber that receives a `PubsubMessage` via a `Pull` call or a push delivery. It must not be populated by the publisher in a `Publish` call.
`publish_time`	`Timestamp` The time at which the message was published, populated by the server when it receives the `Publish` call. It must not be populated by the publisher in a `Publish` call.
`ordering_key`	`string` If non-empty, identifies related messages for which publish order should be respected. If a `Subscription` has `enable_message_ordering` set to `true`, messages published with the same non-empty `ordering_key` value will be delivered to subscribers in the order in which they are received by the Pub/Sub system. All `PubsubMessage`s published in a given `PublishRequest` must specify the same `ordering_key` value.
