--------------------------------
Summary: Add a long running WordCount example
Key: FLINK-16517
URL: https://issues.apache.org/jira/browse/FLINK-16517
Project: Flink
Issue Type: Improvement
Components: Examples
Reporter: Ethan Li
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.
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.
