In Doris, one block has 1024 rows. 1. If the previous ScanKey scan rows multiple blocks, and also the final block has 1024 rows just right. 2. The current ScanKey scan rows with number less than one block. Under the two conditions, if not seek block, the position of prefix shortkey columns is wrong.
