   They are both pyarrow.Tables, but the first one is the result of 
pyarrow.dataset.to_table() with filtering..
   
   First one has 1095 chunks which matches the 1095 parquet files over a 4 year 
period even though I'm only looking at a month of data. This is the result of 
parallelized reads used in pyarrow.dataset..

   The second one only has 9 chunks for a single file..
