> Decouple restart strategy from ExecutionGraph

> Key: FLINK-3187
> URL: https://issues.apache.org/jira/browse/FLINK-3187
> Project: Flink
> Issue Type: Improvement
> Affects Versions: 1.0.0
> Reporter: Till Rohrmann
> Assignee: Till Rohrmann
> Priority: Minor
>
> Currently, the {{ExecutionGraph}} supports the following restart logic:
> Whenever a failure occurs and the number of restart attempts aren't depleted,
> wait for a fixed amount of time and then try to restart. This behaviour can
> be controlled by the configuration parameters {{execution-retries.default}}
> and {{execution-retries.delay}}.
> I propose to decouple the restart logic from the {{ExecutionGraph}} a bit by
> introducing a strategy pattern. That way it would not only allow us to define
> a job specific restart behaviour but also to implement different restart
> strategies. Conceivable strategies could be: Fixed timeout restart,
> exponential backoff restart, partial topology restarts, etc.
> This change is a preliminary step towards having a restart strategy which
> will scale the parallelism of a job down in case that not enough slots are
> available.
