We are currently running ES 2.1 in production and experiencing issues once we need to sort documents.
Our cluster is made of 3 nodes (heap: 15 GB). We have 3 indexes (5 shards). One of our indexes counts more than 310 000 000 documents,
I would like to make a test to run ES 6.3 on another server (and ONLY ONE server). The problem is that I have only 1 server available (4 vCPU, 65 GB...) to run these tests. These tests are not intended to demonstrate any performance but this is more a feasibility test.
The question: How could I do to get the content of ONE index and have it on ONE node?
Many thanks for your help
