---------------------------------------
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.
