   > ound by number of row groups in your parquet file.
   
   I understand what you have said.
   The code`int rg_batchsize = nrgs / batch_size;` means I merge `batch_size` 
rowgroups into one recordbatch, and RecordBatchReader would read the rowgroups 
as one RecordBatch. The reason why I did this was because I could not change 
the parquet file but I wanted to increase the io granularity each thread.
