Because the table in Cow format will copy the previous data file every time the data is updated. Although you use incremental queries, it will still read the latest data file and filter the data you need. In principle, I think it is consistent with the filtering of data read from the whole table. Even the performance is not enough, because it can also do some file filtering operations, although it does not mean much to the COW table. -- This is an automated message from the Apache Git Service.
