Flink Jira Bot updated FLINK-4859:
----------------------------------
Labels: auto-deprioritized-major stale-minor (was:
auto-deprioritized-major)
I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issues has been marked as
Minor but is unassigned and neither itself nor its Sub-Tasks have been updated
for 180 days. I have gone ahead and marked it "stale-minor". If this ticket is
still Minor, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.
> Clearly Separate Responsibilities of StreamOperator and StreamTask
> ------------------------------------------------------------------

> Key: FLINK-4859
> URL: https://issues.apache.org/jira/browse/FLINK-4859
> Project: Flink
> Issue Type: Improvement
> Components: API / DataStream, Runtime / Task
> Reporter: Aljoscha Krettek
> Priority: Minor
> Labels: auto-deprioritized-major, stale-minor
>
> Currently, {{StreamTask}} and {{StreamOperator}} perform a complicated dance
> for certain operations. For example, when restoring from a snapshot, the
> state backends are restored in the {{StreamTask}}, but only after
> {{StreamTask}} calls restore on the operator and the operator asks for the
> backends. There is no clear separation/modularisation with properly defined
> interfaces right now.
> The code works right now but maintainability/understandability could be
> greatly improved.
