public class DatasetInfo implements Serializable
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.

Overrides
getAcl()
public List<Acl> getAcl()
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("[email protected]"), Acl.Role.READER));
Dataset.Builder builder = dataset.toBuilder();
builder.setAcl(acls);
bigquery.update(builder.build()); // API request.

getCreationTime()
public Long getCreationTime()
Returns the time when this dataset was created, in milliseconds since the epoch.

getDatasetId()
public DatasetId getDatasetId()
Returns the dataset identity.
getDefaultCollation()
public String getDefaultCollation()

public Long getDefaultPartitionExpirationMs()

getDefaultTableLifetime()
public Long getDefaultTableLifetime()
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.

getEtag()
Returns the hash of the dataset resource.
getExternalDatasetReference()

getGeneratedId()
public String getGeneratedId()
Returns the service-generated id for the dataset.
getLabels()
public Map<String,String> getLabels()
getLastModified()

since the epoch.
