[GitHub] [iotdb] Alima777 commented on pull request #5821: Fix order by when aligned by device

   Hi, in align by device query, we see each device as one relational table with (device + timestamp) as the primary key. When querying multiple devices, the result is sorted by device order first, and then by timestamp order. Therefore, **it's not a wrong order, but the current standard we defined.**
   
   However, this definition does not satisfy some users' cases indeed. But if modified simply as you did, maybe other users still want the result order before. So we will redefine the semantics in the next version and support these two order at the same time.
