Hi All, We have a 3-node clustered deployment.
Code extract : WriteTransaction writeTxn = dataBroker.newWriteOnlyTransaction(); writeTxn.put() CheckedFuture<> checkedFuture = writeTxn.submit() Scenario : 1) Three nodes in the setup N1, N2, N3 2) N3 is the shard leader. 3) All RPC requests from the NBI are sent to N2. 4) First two requests are successful. 5) Before the third request, N3 goes down and there is NO SHARD LEADER 6) Third RPC request is sent to N2 Now will the checkedFuture value be null or error since there is no shard-leader ? Are there any ways to know the shard-leader is down without blocking on the checkedFuture and send an error in the RPC response to the NBI user ? We are basically hitting this issue while scaling the requests. Regards -Satish
