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. As currently the merge of [1] is blocking further streaming development (it also contains some refactor) I'd like to merge it asap to where it is currently (flink-scala), and let us figure out the project restructure separately. Added a JIRA for the latter. [4] If we choose to restructure the project it will need a commit anyway.
