Which node type is best for indexing requests?

Hi All,

I wonder which node type is best for receiving indexing requests?

Refer to https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-node.html, for heaving indexing cluster, is having dedicated client node(s) for receving indexing requests the best approach? Should client nodes locate on the same physical servers as data nodes to avoid network latency?


Client nodes are best if you can have them.
