-------------------------------

             Summary: Support building pipelined regions from base topology
                 Key: FLINK-14453
                 URL: https://issues.apache.org/jira/browse/FLINK-14453
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Coordination
    Affects Versions: 1.10.0
            Reporter: Zhu Zhu
             Fix For: 1.10.0


Previously pipelined regions can only be built from FailoverTopology. With FLINK-14451 that extends FailoverTopology from base topology, PipelinedRegionComputeUtil can be modified a bit to able to build regions from the base topology.
This is a pre-requisite of FLINK-14312. And also enables SchedulingTopology to provide pipelined region info.

More details see FLINK-14330 and the [design doc|https://docs.google.com/document/d/1f88luAOfUQ6Pm4JkxYexLXpfH-crcXJdbubi1pS2Y5A/edit#].
