Aljoscha Krettek updated FLINK-4859: ------------------------------------ Component/s: Runtime / Task > 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: Major > > 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
