Load testing is crucial with regards to driving your design decisions when it comes to Elastic Search indices. Although there are rule-of-thumb numbers for decisions like index shard count and size, taking the guesswork out helps you root out issues long before they become a problem.
Using a CI server like Jenkins, coupled with custom Gatling tests allows you to easily test your indexes and record results, whilst throwing a large number of virtual users at your cluster with relative ease.
