------------------------------------------------------------
[~aljoscha] Thanks for the link. I feel like it's still not simple enough for
starters. I am looking for a very simple example so starters can focus on
making their first flink job running. WordCount example is a like a hello-world
program in streaming.
We can modify current WordCount example to take a new option so a new Source
can generate data randomly. It will change the current code too much.

> Project: Flink
> Issue Type: Improvement
> Components: Examples
> Reporter: Ethan Li
> Priority: Minor
>
> As far as I know, flink doesn't have a long running WordCount example for
> users to start with or doing some simple tests.
> The closest one is SocketWindowWordCount. But it requires setting up a server
> (nc -l ), which is not hard, but still tedious for simple use cases. And it
> requires human input for the job to actually run.
> I propose to add or modify current WordCount example to have a SourceFunction
> that randomly generates input data based on a set of sentences, so the
> WordCount job can run forever. The generation ratio will be configurable.
> This will be the easiest way to start a long running flink job and can be
> useful for new users to start using flink quickly, or for developers to test
> flink easily.
