I have only done prefetching in a single thread. Theoretically, it can also be implemented in a multi-threaded model, but it requires a relatively large change in the row group segmentation strategy because prefetching requires serial execution of row groups. There is a lack of corresponding test sets to verify the performance benefits of the row group segmentation strategy.
