`labels`	`map (key: string, value: string)` Optional. See Creating and managing labels. An object containing a list of `"key": value` pairs. Example: `{ "name": "wrench", "mass": "1.3kg", "count": "3" }`.
`messageStoragePolicy`	`object (MessageStoragePolicy)` Optional. 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.

`schemaSettings`	`object (SchemaSettings)` Optional. Settings for validating messages published against a schema.

If this field is set, messages published to the topic in the last `messageRetentionDuration` are always available to subscribers.
