             Summary: Enable frame csv reblock
                 Key: SYSTEMML-929
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-929
             Project: SystemML
          Issue Type: Task
            Reporter: Matthias Boehm
            Assignee: Matthias Boehm


We aim to support the old file-based transform and the new frame-based transform at the same time. Both are isolated at compiler/runtime level with separate builtin functions. However, the file-based transform directly consumes csv files, while the frame-based transform requires a normal csv reblock as done for matrices. 

This task will enable the internal flag to inject csv reblocks for frame csv inputs. To support the old transform, we disable this flag whenever a transform call is encountered during compilation - the implication is that the file-based transform and the frame-based transform (over csv files) cannot be used in a mixed manner in a single script.
