timestamp_column

timestamp_column: [column name]

If your data set has a timestamp column that represents the creation time of a field, it is highly recommended configuring it as a timestamp_column.

Elementary anomaly detection tests will use this column to create time buckets and filter the table. It is highly recommended to configure a timestamp column (if there is one). The best column for this would be an updated_at/created_at/loaded_at timestamp for each row (date type also works).

If undefined, default is null (no time buckets).
