   Yes, you are right. Currently, there is only one thread to do `add rows -> send data -> wait in flight`. And actually, `add rows` and `send data` can be done paralleled.
   
   A simple implementation is to use one thread to add rows, and a thread pool to do the data sending. But may double the memory consumption cause it may has 2 row batch in memory 
   same time.
