Hi @lxwithgod .

Messages like asking if i can server tablet for:phone are normal and don't mean that anything is going wrong.

On the other hand, WARN: A tick missed to fire. Node blocks too long! is more concerning. It's not a fatal error (it should recover eventually), but it could indicate there is some kind of communication problem between nodes.

Could you tell a bit about what you are trying to do and how you have your dgraph cluster set up?

[lxwithgod]

hi,I didn't install cluster,i use client in the other machine.i am testing dgraph for my project.maybe because of http-client.but
i use dgraph4j,insert become slower and slower.I don't use index for this node.

Hi @lxwithgod , could you give more details about how you are using HTTP and dgraph4j? How many mutations are you making per transaction?

[lxwithgod]

ManagedChannel channel = ManagedChannelBuilder.forAddress(TEST_HOSTNAME, TEST_PORT).usePlaintext(true).build();
DgraphBlockingStub blockingStub = DgraphGrpc.newBlockingStub(channel);
DgraphClient dgraphClient = new DgraphClient(Collections.singletonList(blockingStub));

    // Set schema

// Operation op = Operation.newBuilder().setSchema("name: string @index(exact) .").build();
// dgraphClient.alter(op);

    // Add data

// System.out.println(json.toString());
LinkedList lj=new LinkedList<>();

    for(int i=1;i<100000000L;i++) {
        HashMap<String,String> json = new HashMap<>();
        json.put("name", "Alice");
        lj.add(json);
        if(i%20000==0){

            Mutation mu =
                    Mutation.newBuilder()
                            .setSetJson(ByteString.copyFromUtf8(Common.objectAsString(lj)))
                            .build();
            DgraphClient.Transaction transaction = dgraphClient.newTransaction();
            transaction.mutate(mu);
            transaction.commit();
            System.out.println(i);
            lj.clear();

        }

    }

I'm going to close this ticket, I didn't realise this was a crosspost until just now. Let's solve the issue over at hypermodeinc/dgraph4j#30
