public boolean containsTargetColumnCorrelations(String key)
Output only. Correlations between
TablesDatasetMetadata.target_column_spec_id,
and other columns of the
TablesDatasetMetadataprimary_table.
Only set if the target column is set. Mapping from other column spec id to
its CorrelationStats with the target column.
This field may be stale, see the stats_update_time field for
for the timestamp at which these stats were last updated.

Returns

public TablesDatasetMetadata getDefaultInstanceForType()
Returns
public String getMlUseColumnSpecId()
column_spec_id of the primary table column which specifies a possible ML
use of the row, i.e. the column will be used to split the rows into TRAIN,
VALIDATE and TEST sets.
Required type: STRING.
This column, if set, must either have all of TRAIN, VALIDATE, TEST
among its values, or only have TEST, UNASSIGNED values. In the latter
case the rows with UNASSIGNED value will be assigned by AutoML. Note
that if a given ml use distribution makes it impossible to create a "good"
model, that call will error describing the issue.
If both this column_spec_id and primary table's time_column_spec_id are not
set, then all rows are treated as UNASSIGNED.
NOTE: Updates of this field will instantly affect any other users
concurrently working with the dataset.
string ml_use_column_spec_id = 4;
| Type | Description |
| String | The mlUseColumnSpecId.
|
public ByteString getMlUseColumnSpecIdBytes()

VALIDATE and TEST sets.
Required type: STRING.
This column, if set, must either have all of TRAIN, VALIDATE, TEST
