morningman opened a new issue #2045: Too many `rollback transaction from engine successfully` log in be.INFO
URL: https://github.com/apache/incubator-doris/issues/2045
 
 
   **Describe the bug**
   When loading data, there are too many logs in be.INFO like:
   
   `rollback transaction from engine successfully xxxx`
   
   This is because BE will always rollback transactions corresponding to `no-data-loaded`
   partitions. 
   
   **How to resolve**
   We should only begin transactions for partitions when there is data to be loaded.
   So, we should open the DeltaWriter when first data comes.
