Class DatasetInfo (2.42.3)

Google BigQuery Dataset information. A dataset is a grouping mechanism that holds zero or more tables. Datasets are the lowest level unit of access control; you cannot control access at the table level. See Also: Managing Jobs, Datasets, and Projects

Returns a builder for a DatasetInfo object given it's identity.

Returns a builder for a DatasetInfo object given it's user-defined id.

Returns a builder for the DatasetInfo object given it's user-defined project and dataset ids.

Returns a DatasetInfo object given it's identity.

Returns a DatasetInfo object given it's user-defined id.

Returns the dataset's access control configuration.

Update the ACLs for a dataset.

 Dataset dataset = bigquery.getDataset(DatasetId.of("my_dataset"));
 List<Acl> beforeAcls = dataset.getAcl();

 // Make a copy of the ACLs so that they can be modified.
 ArrayList<Acl> acls = new ArrayList<>(beforeAcls);
 acls.add(Acl.of(new Acl.User("sample.bigquery.dev@gmail.com"), Acl.Role.READER));
 Dataset.Builder builder = dataset.toBuilder();
 builder.setAcl(acls);

 bigquery.update(builder.build());  // API request.

Returns the time when this dataset was created, in milliseconds since the epoch.

Returns the dataset identity.

Returns the default lifetime of all tables in the dataset, in milliseconds. Once this property is set, all newly-created tables in the dataset will have an expirationTime property set to the creation time plus the value in this property, and changing the value will only affect new tables, not existing ones. When the expirationTime for a given table is reached, that table will be deleted automatically. If a table's expirationTime is modified or removed before the table expires, or if you provide an explicit expirationTime when creating a table, that value takes precedence over the default expiration time indicated by this property.

Update the default table expiration time for a dataset.

 Dataset dataset = bigquery.getDataset(DatasetId.of("my_dataset"));
 Long beforeExpiration = dataset.getDefaultTableLifetime();

 Long oneDayMilliseconds = 24 * 60 * 60 * 1000L;
 Dataset.Builder builder = dataset.toBuilder();
 builder.setDefaultTableLifetime(oneDayMilliseconds);
 bigquery.update(builder.build());  // API request.
 

Returns a user-friendly description for the dataset.

Returns the hash of the dataset resource.

Returns information about the external metadata storage where the dataset is defined. Filled out when the dataset type is EXTERNAL.

Returns a user-friendly name for the dataset.

Returns the service-generated id for the dataset.

Return a map for labels applied to the dataset. See Also: Labeling Datasets

Returns the time when this dataset or any of its tables was last modified, in milliseconds since the epoch.

Returns the geographic location where the dataset should reside. See Also: Dataset Location

Returns an URL that can be used to access the resource again. The returned URL can be used for get or update requests.

Returns a builder for the dataset object.
