}
Fields
parent

string

Required. The project to which the request should be attributed in the following form: projects/{project}/locations/{location}/dataProducts/{data_product}.
pageSize

integer

ListDataAssetsResponse

JSON representation 
{
  "dataAssets": [
    {
      object (DataAsset)
    }
  ]
}
Fields
dataAssets[]

object (DataAsset)

The list of data assets that match the list request.

DataAsset

JSON representation 
{
  "name": string,
  "uid": string,
  "createTime": string,
  "updateTime": string,
  "etag": string,
  "labels": {
    string: string,
    ...
  },

  "accessGroupConfigs": {
    string: {
      object (AccessGroupConfig)
    },
    ...
  }
}
Fields
name

string

Identifier. Resource name of the data asset. Format: projects/{project_id_or_number}/locations/{location_id}/dataProducts/{data_product_id}/dataAssets/{data_asset_id}
uid

string

Output only. System generated globally unique ID for the data asset. This ID will be different if the data asset is deleted and re-created with the same name.
createTime

string (Timestamp format)

Output only. The time at which the data asset was created.

Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z", "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30".
updateTime

string (Timestamp format)

Output only. The time at which the data asset was last updated.

Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z", "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30".
etag

string

Optional. This checksum is computed by the server based on the value of other fields, and may be sent on update and delete requests to ensure the client has an up-to-date value before proceeding.
labels

map (key: string, value: string)

Optional. User-defined labels for the data asset.

Example:

{ "environment": "production", "billing": "marketing-department" }

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

string

Required. Immutable. Full resource name of the cloud resource represented by the data asset. This must follow https://cloud.google.com/iam/docs/full-resource-names. Example: //bigquery.googleapis.com/projects/my_project_123/datasets/dataset_456/tables/table_789 Only BigQuery tables and datasets are currently supported. Data asset creator must have getIamPolicy and setIamPolicy permissions on the resource. Data asset creator must also have resource specific get permission, for instance, bigquery.tables.get for BigQuery tables.
accessGroupConfigs

map (key: string, value: object (AccessGroupConfig))

Optional. Access groups configurations for this data asset.

The key is DataProduct.AccessGroup.id and the value is AccessGroupConfig.

Example:

 {
   "analyst": {
     "iamRoles": ["roles/bigquery.dataViewer"]
   }
 }

Currently, at most one IAM role is allowed per access group. For providing multiple predefined IAM roles, wrap them in a custom IAM role as per https://cloud.google.com/iam/docs/creating-custom-roles.

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

nanos

integer

Non-negative fractions of a second at nanosecond resolution. This field is the nanosecond portion of the duration, not an alternative to seconds. Negative second values with fractions must still have non-negative nanos values that count forward in time. Must be between 0 and 999,999,999 inclusive.
