[jira] [Created] (SYSTEMML-1637) Memory-efficiency csv/dataset - binary block converters

Matthias Boehm created SYSTEMML-1637:
----------------------------------------

             Summary: Memory-efficiency csv/dataset - binary block converters
                 Key: SYSTEMML-1637
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-1637
             Project: SystemML
          Issue Type: Sub-task
            Reporter: Matthias Boehm


This task aims to make the converters for (1) csv to binary block, and (2) dataset to binary block more memory-efficient via a lazy iterator, which reduces the map output memory requirement from all blocks of a partition to a single row of blocks.
