    string: string,
    ...
  },
  "messageStoragePolicy": {
    object (MessageStoragePolicy)
  },
  "kmsKeyName": string,
  "schemaSettings": {
    object (SchemaSettings)
  },
  "satisfiesPzs": boolean,
  "messageRetentionDuration": string
}
Fields
name

string

Required. Name of the topic. Format is projects/{project}/topics/{topic}.
labels

map (key: string, value: string)

See Creating and managing labels.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.
messageStoragePolicy

Policy constraining the set of Google Cloud Platform regions where messages published to the topic may be stored. If not present, then no constraints are in effect.
kmsKeyName

The resource name of the Cloud KMS CryptoKey to be used to protect access to messages published on this topic.

The expected format is projects/*/locations/*/keyRings/*/cryptoKeys/*.
schemaSettings

object (SchemaSettings)

Settings for validating messages published against a schema.
satisfiesPzs

boolean

Reserved for future use. This field is set only in responses from the server; it is ignored if it is set in any requests.
messageRetentionDuration

string (Duration format)

Indicates the minimum duration to retain a message after it is published to the topic. If this field is set, messages published to the topic in the last messageRetentionDuration are always available to subscribers. For instance, it allows any attached subscription to seek to a timestamp that is up to messageRetentionDuration in the past. If this field is not set, message retention is controlled by settings on individual subscriptions. Cannot be more than 31 days or less than 10 minutes.

A duration in seconds with up to nine fractional digits, terminated by 's'. Example: "3.5s".

MessageStoragePolicy

A policy constraining the storage of messages published to the topic.

JSON representation 
{
  "allowedPersistenceRegions": [
    string
  ]
}
Fields
allowedPersistenceRegions[]

string

A list of IDs of GCP regions where messages that are published to the topic may be persisted in storage. Messages published by publishers running in non-allowed GCP regions (or running outside of GCP altogether) will be routed for storage in one of the allowed regions. An empty list means that no regions are allowed, and is not a valid configuration.
