Expand description
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] (https://cloud.google.com/pubsub/quotas) for more information about message limits.
Fields
data: Vec<u8>
The message data field. If this field is empty, the message must contain at least one attribute.
attributes: HashMap<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: Option<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.
