Dear Team,

I am new in MongoDB and now trying to set up its a cluster for evaluation purpose.

Case: we are using only one instance of mongos and after some time run one more instance of it, but My java client is not able to send the request to the newly added mongos instance.

I think java client should add automatically new host IP of mongos in its connection pool.

Please suggest if any configuration is required for this.

Hi Sumit,

You can specify a list of mongos instances, for example using ServerAddress:

MongoClient mongoClient = MongoClients.create(
        MongoClientSettings.builder()
                .applyToClusterSettings(builder ->
                        builder.hosts(Arrays.asList(
                                new ServerAddress("mongos_01", 27019),
                                new ServerAddress("mongos_02", 27019))))
                .build());
