Gábor Hermann commented on FLINK-4947:
--------------------------------------
[~jgrier] Thanks for the clarification! I agree with all your points.
Could we split up this issue to
1. all config should be configurable via flink-conf.yaml
2. all flink-conf.yaml config should be available via command line
I would be happy to assess 2.
> Make all configuration possible via flink-conf.yaml and CLI.

> I think it's important to make all configuration possible via the
> flink-conf.yaml and the command line.
> As an example: To enable "externalizedCheckpoints" you must actually call
> the StreamExecutionEnvironment#enableExternalizedCheckpoints() method from
> your Flink program.
> Another example of this would be configuring the RocksDB state backend.
> I think it important to make deployment flexible and easy to build tools
> around. For example, the infrastructure teams that make these configuration
> decisions and provide tools for deploying Flink apps, will be different from
> the teams deploying apps. The team writing apps should not have to set all
> of this lower level configuration up in their programs.
