For example, consider multiple BEs in Apache Doris. The load is not balanced during concurrent imports. At the same checkpoint, multiple stream load tasks are directed to the same BE, causing server pressure on the backends because the Pos variables are the same within the checkpoint. To address this, we can calculate the destination BE using both the subTaskId and Pos variables.
