Unfortunately, as far as I know there is no way to make this query work in 
multiple partitions, since some partitions are empty and your source is 
unbounded. If partitioning is not critical, you can set the 
`datafusion.execution.target_partitions=1`. That would solve the problem.
   
   I still cannot understand. The results of `Option<RecordBatche>` from  
multiple partitions merge one to return, if one of it has empty data, then the 
result from that one is `None`. Why it give me an error? If it is a problem of 
timeout, can I change the timeout config (maybe it is in tokio side)?.
