> The design doc
https://issues.apache.org/jira/secure/attachment/13047193/observer_reads_in_rbf_proposal_simbadzina_v2.pdf
is very helpful . But the Third party communication(pdf) in the
observer_reads_in_rbf_proposal_simbadzina_v2.pdf is too blurry to read , and
the pdf link
https://drive.google.com/file/d/1851oaVeayiKKbNFSa93G5CS-bXXZY7BM/view?usp=sharing
is does not exist.

> Can anyone put it again？ Thanks very much
I've replaced the file with one with refreshed links.

I've uploaded the third party reads pdf to Jira as well:

> Changes will need to occur to the router to support the new observer node.
> One such change will be to make the router understand the observer state,
> e.g. {{{}FederationNamenodeServiceState{}}}.
> This patch captures the state of all namespaces in the routers and propagates
> it to clients. A follow up patch will change router behavior to direct
> requests to the observer.
