--------------------------------------

             Summary: Read a reasonable amount of data per chunk.
                 Key: BEAM-11249
                 URL: https://issues.apache.org/jira/browse/BEAM-11249
             Project: Beam
          Issue Type: Bug
          Components: sdk-py-core
            Reporter: Robert Bradshaw


In read_csv (and others), we are reading only 100 rows or so at a time. This 
gives kb-sized chunks, the reader is likely optimal in the mb-sized ranges.
