[jira] [Commented] (YARN-7898) [FederationStateStore] Create a proxy chain for FederationStateStore API in the Router

    [ https://issues.apache.org/jira/browse/YARN-7898?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16528158#comment-16528158 ] 

Giovanni Matteo Fumarola commented on YARN-7898:
------------------------------------------------

Thanks [~elgoiri]. Yes we are relying on the StateStore Facade in the Router for caching.

We can open a different Jira to work on RPC since it will require extra work for the protocol.

I will let Yetus run the [^YARN-7898-YARN-7402.proto.patch].

> As detailed in the proposal in the umbrella JIRA, we are introducing a new component that routes client request to appropriate FederationStateStore. This JIRA tracks the creation of a proxy for FederationStateStore in the Router.
