Hi, all.

```
as we know that , in a elasticsearch cluster, different configurations 

```

have different effects.

```
like that:
node.master: true and node:data: false ==> it will be a 

```

"coordinator"  
node.master: false and node.data: true ==\> it will be a  
"workhorse", just to store data.  
node.master: false and node.data:false ==\> it act as a "search  
load balancer"

```
if we have a elasticsearch cluster contains 10 node.
how can we assign roles for these 10 nodes?

```

We have a 25 node cluster, with 3 master only nodes that we use as search  
nodes, then the rest as data only.

But it depends on what your workload is.
