> Disentangle ExecutionConfig
> ---------------------------
>
> Key: FLINK-3642
> URL: https://issues.apache.org/jira/browse/FLINK-3642
> Project: Flink
> Issue Type: Improvement
> Components: API / DataSet, API / DataStream
> Affects Versions: 1.1.0
> Reporter: Till Rohrmann
> Priority: Major
> Labels: stale-major
>
> Initially, the {{ExecutionConfig}} started out being a configuration to
> configure the behaviour of the system with respect to the associated job. As
> such it stored information about the restart strategy, registered types and
> the parallelism of the job. However, it happened that the {{ExecutionConfig}}
> has become more of an easy entry-point to pass information into the system.
> As such, the user can now set arbitrary information as part of the
> {{GlobalJobParameters}} in the {{ExecutionConfig}} which is piped to all
> kinds of different locations in the system, e.g. the serializers, JM,
> ExecutionGraph, TM, etc.
> This mixture of user code classes with system parameters makes it really
> cumbersome to send system information around, because you always need a user
> code class loader to deserialize it. Furthermore, there are different means
> how the {{ExecutionConfig}} is passed to the system. One is giving it to the
> {{Serializers}} created in the JavaAPIPostPass and another is giving it
> directly to the {{JobGraph}}, for example. The problem is that the
> {{ExecutionConfig}} contains information which is required at different
> stages of a program execution.
> I think it would be beneficial to disentangle the {{ExecutionConfig}} a
> little bit along the lines of the different concerns for which the
> {{ExecutionConfig}} is used currently.
