> Python API for streaming applications
> -------------------------------------
>                 Key: FLINK-5886
>                 URL: https://issues.apache.org/jira/browse/FLINK-5886
>             Project: Flink
>          Issue Type: New Feature
>          Components: Python API
>            Reporter: Zohar Mizrahi
>            Assignee: Zohar Mizrahi
> A work in progress to provide python interface for Flink streaming APIs. The core technology
is based on jython and thus imposes two limitations: a. user defined functions cannot use
python extensions. b. the python version is 2.x
> The branch is based on Flink release 1.2.0, as can be found here:
> https://github.com/zohar-pm/flink/tree/python-streaming
> In order to test it, someone can use IntelliJ IDE. Assuming IntelliJ was setup properly
(see: https://ci.apache.org/projects/flink/flink-docs-release-1.3/internals/ide_setup.html),
one can run/debug {{org.apache.flink.python.api.PythonStreamBinderTest}}, which in return
will execute all the tests under {{/Users/zohar/dev/pm-flink/flink-libraries/flink-python/src/test/python/org/apache/flink/python/api/streaming}}
