> Key: FLINK-8180
> URL: https://issues.apache.org/jira/browse/FLINK-8180
> Project: Flink
> Issue Type: Improvement
> Components: Library / Graph Processing (Gelly)
> Affects Versions: 1.5.0
> Reporter: Greg Hogan
> Priority: Minor
> Labels: auto-deprioritized-major, auto-unassigned
>
> The change in 1.4 of algorithm results from Tuples to POJOs broke the writing
> of results as csv. Testing this was and is a challenge so was not done. There
> are many additional improvements which can be made based on recent
> improvements to the Gelly framework.
> Result hash and analytic results should always be printed to the screen.
> Results can optionally be written to stdout or to a file. In the latter case
> the result hash and analytic results (and schema) will also be written to a
> top-level file.
> The "verbose" output strings can be replaced with json which is just as
> human-readable but also machine readable. In addition to csv and json it may
> be simple to support xml, etc. Computed fields will be optionally printed to
> screen or file (currently these are always printed to screen but never to
> file).
> Testing will be simplified since formats are now a separate concern from the
> stream.
> Jackson is available to Gelly as a dependency provided in the Flink
> distribution but we may want to build flink-gelly-examples as an uber jar in
> order to include additional modules (which may require a direct dependency on
> Jackson, which would require checkstyle suppressions around the unshaded
> jackson imports).
