Interface FlowStepStrategy<Config>

    public interface FlowStepStrategy<Config>

The FlowStepStrategy interface allows for on the fly customization of `FlowStep` configuration values before they are submitted to the underlying platform.

Use a strategy instance to change the display name for a job, or in the case of Hadoop, the number of mapper or reducer instances.

Note, to change the configuration information, `FlowStep.getConfig()` must be called to get access to the current configuration.

If any, the completed predecessor steps are provided so that the predecessors can be inspected via the `FlowStepStats` interface for any information that may influence the current job.

It is also possible to block submission of the job by blocking in this method.

Method Summary
`void` `apply(Flow<Config> flow, List<FlowStep<Config>> predecessorSteps, FlowStep<Config> flowStep)`
