Xiaogang Shi commented on FLINK-12761:
--------------------------------------
I think it's a good idea to enable fine-grained resource management in Flink.
I'ver read the design document and found many details omitted in the document.
As ResourceManager is a critical component in Flink and has many bugs right now
(especially YarnResourceManager), it's appreciated that you can provide more
details in your design document.
> Fine grained resource management

> Key: FLINK-12761
> URL: https://issues.apache.org/jira/browse/FLINK-12761
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Configuration
> Affects Versions: 1.8.0, 1.9.0
> Reporter: Tony Xintong Song
> Assignee: Tony Xintong Song
> Priority: Major
> Labels: Umbrella
>
> This is an umbrella issue for enabling fine grained resource management in
> Flink.
> Fine grained resource management is a big topic that requires long term
> efforts. There are many issues to be addressed and designing decisions to be
> made, some of which may not be resolved in short time. Here we propose our
> design and implementation plan for the upcoming release 1.9, as well as our
> thoughts and ideas on the long term road map on this topic.
> A practical short term target is to enable fine grained resource management
> for batch sql jobs only in the upcoming Flink 1.9. This is necessary for
> batch operators added from blink to achieve good performance.
> Please find detailed design and implementation plan in attached docs. Any
> comment and feedback are welcomed and appreciated.
