I am trying to know which would be the performance improvement of running a 3 node cluster over a 1 node cluster.
In order to do this, I have installed esrally and run this way
- esrally --distribution-version=6.0.0 // running locally on 1 node
- esrally --distribution-version=6.0.0 --target-hosts=172.16.8.117:9200,172.16.8.118:9200,172.16.8.119:9200
To my surprise the results are pretty much the same, it looks as rally has run the same workload 3 times instead of 1 workload shared amongst the 3 nodes.
Is there any way to achive what I want?
