Sets the time when this table expires, in milliseconds since the epoch. If not present, the table will persist indefinitely. Expired tables will be deleted and their storage reclaimed.
When used with BigQuery#update(TableInfo, TableOption...), setting labels to null removes all labels; otherwise all keys that are mapped to null values are removed and other keys are updated to their respective values.
