Hi, thank you all for supporting this proposal!
Recently, I will split this huge PR to small PRs.
Thank you again!

Great! It looks like there are no other nothing blockers.
@zhangjian <1361320...@qq.com> If no other furthermore comments, we should
go to the next step:
a. Create a dev branch for this proposal.
b. Split this huge PR to some small JIRA and PRs.
c. Involve some folks to review PR.
Please ping her
Thanx for the details, sounds cool, good luck with the feature!!!

Thank you for taking the time to review this proposal.
Your opinion does point out the key issues to designing an asynchronous router,
but my proposal can address these issues:
1. My design does not affect the functionality of existing synchronous routers
in throwing stanby or retry exceptions an
Thanx folks, I had a very quick pass on the PDF and it looks good.
Maybe some doubts around the fact where it was mentioned that if a
Namenode returns a StandbyException or something on similar lines, the
Router will retry, I think we have some logic in RouterRpcClient
checking for such case, if i
Sounds good. Thanks for sharing your findings.

Hello everyone, I conducted a performance comparison test between sync and

Hello everyone, currently, I have tested the performance of async and sync
router for a downstream ns:
1. The throughput, CPU, and thread performance of the async router are better
than those of the sync router, and its memory performance is within an
acceptable range compared to the synchronous
Great. Thanks for your addendum information.

Any more feedback for this proposal?
IMO The feature of asynchronous router RPC is a helpful improvement. For my
internal practice, it will improve the throughput of requests forward
significantly
and is very val
Hi, Sangjin Lee, thank you for your attention. I will use my free time to do a
performance comparison recently.

Thanks for the great proposal, Zhangjian. On point #3, I suspect it should
be fairly straightforward to create a small isolated synthetic test to
prove (or disprove) the benefits of this approach. By driving a controlled
amount of requests per second, you could see latency, memory, CPU, etc.

Hi, xiaoqiao he, thank you for your reply.
1.Currently, the server and client protocols within router can be implemented
by extends existing protocols and adding asynchronous functionality, so it will
not affect existing synchronization protocols.

Thanks for this great proposal!
Some questions after reviewing the design doc (sorry didn't review PR
carefully which is too large.)
1. This solution will involve RPC framework update, will it affect other
modules and how to
keep other modules off these changes.
2. Some RPC requests should be forw
Thank you for your positive attitude towards this feature. You can debug the
UTs provided in PR to better understand the current asynchronous calling
function.

Excited to see this feature as well. I'll spend more time understanding the
proposal and implementation.

Hi, Yuanbo liu, thank you for your interest in this feature, I think the
difficulty of an asynchronous router is not only to implement asynchronous
functions, but also to consider the readability and reusability of the code, so
as to facilitate the development of the community. I also planned t
Nice to see this feature brought up. I tried to implement this feature in
our internal clusters, and know that it's a very complicated feature, CC
hdfs-dev to bring more discussion.
By the way, I'm not sure whether virtual thread of higher jdk will help in
this case.
