I have a cluster include 7 hot nodes.
I tested with only 1 node, that config was: 1 shard/index ==> indexing document rate was: 17k documents/s,
But, when I push to 7 nodes with config: 7 shard/index (1 shard/ 1 node), node.master: true, node.data: true ==> each node has indexing document rate is: 9k documents/s
All both test case, replication number is 0
Can I increase indexing document rate?
Thanks!
