@simbadzina @omalley @melissayou I create a draft PR, and have some different points, like:

Proxy always with AlignmentContext, like RouterGSIContext which contains a boolean flag, like enableObserverRead
Always update the lastSeenStateId from active
If enableObserverRead is false, updateRequestState will not set lastSeenStateId in RPCHeader
It's easily to dynamically reconfigure enableObserverRead.

I'm hope that we can continue push this Feature forward. Please help me review it.

@simbadzina If you want to continue work for this feature, feel free to take over it. Thanks~

…propagate it between routers and clients.

omalley

I have a couple of top level concerns:

All clients will get all of the namespaces in their federated state ids.
If the number of name spaces goes over the maximum, currently we'll msync to all of the namespaces, which will destroy performance.
It looks to me like Server.getCurCall() is set when both the AlignmentContexts are updated (from the NN and to the client). That implies that we could use them to make smaller changes in this patch and only include the namespaces that the specific client cares about.

…propagate it between routers and clients. Fixes apache#4311 Signed-off-by: Owen O'Malley <oomalley@linkedin.com>

LiuGuH · 2023-09-12T06:57:27Z

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. https://issues.apache.org/jira/secure/attachment/13062835/observer_reads_in_rbf_proposal_simbadzina_v2.pdf

I've uploaded the third party reads pdf to Jira as well: https://issues.apache.org/jira/secure/attachment/13062830/rbf_observer_reads%20-%20third_party_reads.pdf
