   > Is there a way to write combined schema in this case?
   
   @arina-ielchiieva , thank you for your comment. 
   
   I can try to make a combined scheme, but:
   - What type of field should be written if the first BatchSchema contains 
field "A" with type "bigint", and the second - field "A" with type "varchar"? 
The last one wins?
   - What about union vectors?
