## What is the purpose of the change When one task has multiple inputs, and the unaligned checkpoint will be disabled for all inputs once one input exchange does not support unaligned checkpoint. It caused no inflight buffers, but `UnalignedCheckpointRescaleWithMixedExchangesITCase.testRescaleFromUnalignedCheckpoint` always wait for checkpoint with inflight buffers. Explicitly specifying rebalance can avoid the forward exchange.
