Hi everyone,

I noticed that every time I create a new node, it takes maybe 10 or  
more seconds.

```
        Node node = nodeBuilder().node();
        Client client = node.client(); //this line takes longer than

```

expected

If I keep adding new documents under the same index, should they be  
stored on a single node? At what point I should switch to a new (or  
next) client node? Is there a limit of what load a single node or  
single index can handle?

Thank you,  
Eugene.

Hey,  
Clients should be instantiated once and shared between threads. The  
client connects to the entire cluster, so no need to switch the client  
in your app.

Indexes can get very large, and with sharding there is no hard limit  
other than disk and ram.

Hope this helps,  
Paul
