Gyula Fora commented on FLINK-13566:
------------------------------------
I don't think there is a good enough reason unfortunately. I believe everything
related to checkpointing should be configurable through the flink-conf.yaml
(just like the state backends)
> Support checkpoint configuration through flink-conf.yaml

> Key: FLINK-13566
> URL: https://issues.apache.org/jira/browse/FLINK-13566
> Project: Flink
> Issue Type: New Feature
> Components: Runtime / Checkpointing, Runtime / Configuration
> Reporter: Gyula Fora
> Priority: Major
>
> Currently basic checkpointing configuration happens through the
> StreamExecutionEnvironment and the CheckpointConfig class.
> There is no way to configure checkpointing behaviour purely from the
> flink-conf.yaml file (or provide a default checkpointing behaviour) as it
> always needs to happen programmatically through the environment.
> The checkpoint config settings are then translated down to the
> CheckpointCoordinatorConfiguration which will control the runtime behaviour.
> As checkpointing related settings are operational features that should not
> affect the application logic I think we need to support configuring these
> params through the flink-conf yaml.
> In order to do this we probably need to rework the CheckpointConfig class so
> that it distinguishes parameters that the user actually set from the defaults
> (to support overriding what was set in the conf).
