Question

我正在使用Mongo java异步驱动程序v3.2使用以下测试。我可以看到调用了回调（在Mongo集合上使用insertOne调用注册的回调）。我可以看到测试客户端能够连接到mongos进程（最后附加的日志）。我在Mongo看不到任何文件。我启用了数据库集合以进行分片，我也可以从mongos进程运行shard status命令。关于我在设置中可能配置错误的想法？

        CountDownLatch latch = new CountDownLatch(1);
        SingleResultCallback<Void> callbackWhenFinished = new SingleResultCallback<Void>() {
            @Override
            public void onResult(final Void result, final Throwable t) {
                System.out.println("Operation Finished!");
                latch.countDown();
            }
        };
final Document doc = new Document("name", "MongoDB")
                .append("type", "database")
                .append("count", 1)
                .append("info", new Document("x", 203).append("y", 102));
        collection.insertOne(doc, callbackWhenFinished);
        latch.await();

Answer 1

通过确保正确配置mongo群集（查询路由器，cofig服务器和具有副本集的mongo分片）解决了该问题。完成此操作后，我可以看到插入被添加到分片（以及达到迁移阈值后的多个分片）。希望它能帮助别人

将文档插入mongo shard
