clearMlUseColumnSpecId()
public TablesDatasetMetadata.Builder clearMlUseColumnSpecId() 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.
