peterxcli opened a new pull request, #1490:
URL: https://github.com/apache/ratis/pull/1490

   ## What changes were proposed in this pull request?
   
   * Refactored `ReadStreamManagement` to perform an asynchronous 
linearizability check using a "dummy read" request before invoking the state 
machine for read-only queries. The state machine query is only performed if the 
check succeeds, and an appropriate reply is sent if it fails.
   * Updated `RaftServerImpl` to recognize and handle dummy read requests by 
returning a success reply immediately, avoiding unnecessary state machine 
queries.
