-------------------------------
Summary: Introduce a unified topology interface
Key: FLINK-14330
URL: https://issues.apache.org/jira/browse/FLINK-14330
Project: Flink
Issue Type: Sub-task
Components: Runtime / Coordination
Affects Versions: 1.10.0
Reporter: Zhu Zhu
Fix For: 1.10.0
When working on FLINK-14312 to partition {{JobGraph}} into logical pipelined
regions, I found that we can hardly reuse the existing util
{{PipelinedRegionComputeUtil#computePipelinedRegions(..)}} to do it since it's
based on the {{FailoverTopology}}.
To avoid code duplication, we need a unified topology base for
{{FailoverTopology}} and {{JobGraph/LogicalTopology}}.
Besides that, the inconsistency of {{FailoverTopology}} and
{{SchedulingTopology}} is also causing troubles for development and performance.
That's why I'd propose to unify the interfaces all these topologies. More
details can be found in this [design
doc|https://docs.google.com/document/d/1f88luAOfUQ6Pm4JkxYexLXpfH-crcXJdbubi1pS2Y5A/edit#].
