Zhu Zhu commented on FLINK-14330:
---------------------------------
Thanks [~trohrmann] for the feedback!
I will use this ticket to introduce the base topology interface
Here are the following tasks:
FLINK-14450 to change SchedulingTopology to extend base topology
FLINK-14451 to change FailoverTopology to extend base topology
FLINK-14452 to keep only one execution topology in scheduler
FLINK-14453 to support building pipelined regions from base topology
Could you assign them to me?
> 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
> Assignee: Zhu Zhu
> Priority: Major
> 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?usp=sharing].
