How Java client send the data source to the cluster?

```auto
bulkRequest.add(new IndexRequest().source(object));

client.bulk(_bulkRequest, RequestOptions.DEFAULT);

```

What exactly it does after converting the data to JSON?  
Does it compress it?  
How it transferred to the cluster?

It's done using the same HTTP REST API you can call with curl.

You should split it in multiple calls. Like 10000 by 10000.
