Do we need the final '\n' ?
> Add an adapter for Apache Flink-Streaming
> -----------------------------------------
>
> Key: SAMOA-16
> URL: https://issues.apache.org/jira/browse/SAMOA-16
> Project: SAMOA
> Issue Type: New Feature
> Reporter: Paris Carbone
> Assignee: Gianmarco De Francisci Morales
>
> Apache Flink-Streaming is a new system for distributed stream processing
> built for unique and flexible high level stream transformations. A Flink
> adapter for Samoa should be able to translate a Samoa Task topology into
> Flink streaming transformations. Some of the challenges are the compositional
> topology support, circle detection and their translation to Flink iterations.
