   - [X] I had searched in the

found no similar issues.
   
   
   ### Description
   
   Supports vectorization of spark load in BE load stage.
   - read link
      - PushBrokerReader supports get_next_block()
      - ParquetScanner ---> VParquetScanner
   - write link
      already supported by vec compaction pr #8438 
   
   
   ### Use case
   
   For the convenience of development, I  decided to set a switch in be.conf 
for this feature. 
   It will be merged into session variable later.
   
   be.conf
   ```
   # false for default
   spark_load_vectorized = true;
   ```
