> Currently the snapshot process contains the synchronous and asynchronous steps. When a StreamTask going to finish, there might be some pending checkpoints that are still running their asynchronous step. Currently StreamTask would abort these pending checkpoints since checkpoints after tasks finished are not support, and it need to be changed to StreamTask wait for these pending checkpoint to finish.
