[jira] [Commented] (FLINK-9192) Undo parameterization of StateMachine Example

["Kostas Kloudas (JIRA)" <ji...@apache.org>]

Kostas Kloudas commented on FLINK-9192:
---------------------------------------

These changes were made in the context of the end-to-end test for High Availability.

It was an intermediate step until the general purpose testing job is written, which will replace the StateMachine job in the test.

That said, I am totally up for undoing the changes.

> The example has been changed to add parametrization and a different sink.
> I would vote to undo these changes, the make the example less nice and use non-recommended sinks:
>   - For state backend, incremental checkpoints, async checkpoints, etc. having these settings in the example blows up the parameter list of the example and distracts from what the example is about.
>   - If the main reason for this is an end-to-end test, then these settings should go into the test's Flink config.
>   - The {{writeAsText}} is a sink that is not recommended to use, because it is not integrated with checkpoints and has no well defined semantics.
