- Tables

Output only. Stats of the series of values in the column. This field may be stale, see the ancestor's Dataset.tables_dataset_metadata.stats_update_time field for the timestamp at which these stats were last updated. |
| top_correlated_columns |
Sequence[google.cloud.automl_v1beta1.types.ColumnSpec.CorrelatedColumn]
