Subject [jira] [Created] (FLINK-1340) Project restructure
Date Thu, 25 Dec 2014 17:26:13 GMT
Márton Balassi created FLINK-1340:

             Summary: Project restructure
                 Key: FLINK-1340
                 URL: https://issues.apache.org/jira/browse/FLINK-1340
             Project: Flink
          Issue Type: Task
          Components: Java API, Scala API, Streaming
    Affects Versions: 0.9
            Reporter: Márton Balassi

During a recent PR of the streaming scala api [1] arose the issue of possibly changing the
project structure. For the discussion it seems to me that we should address this as a separate
issue. Things to note:

   * According to Stephan for the batch part, there are discussions
to combine the "flink-core", "flink-java" projects, possibly also the "flink-scala" project.
We are starting to see too many interdependencies. [2]
   * Streaming is currently under flink-addons, but we are positive that for the next version
we can come up with a fairly stable api if needed. We would like to have it top level eventually.
   * Minor issue to keep in mind: Developing our projects with both scala and java nature
seems a bit flaky at the moment at least for Eclipse. [3] Proposed solutions are also there,
just let us make sure to give new developers a smooth experience with Flink.

I personally like the following suggestion: [2]

We could, in the next version, go for something like 
- flink-core (core and batch, java & scala) 
- flink-streaming (java & scala) 
- flink-runtime 
- ...

Ufuk also +1'd this.
