May I suggest you look at the following resources about sizing: [https://www.elastic.co/elasticon/conf/2016/sf/quantitative-cluster-sizing](https://www.elastic.co/elasticon/conf/2016/sf/quantitative-cluster-sizing) > **[How many shards should I have in my Elasticsearch cluster?](https://www.elastic.co/blog/how-many-shards-should-i-have-in-my-elasticsearch-cluster)** > > If you are looking for practical guidelines around how many indices and shards to have in your cluster, this blog post will help you avoid common pitfalls. https://www.slideshare.net/slideshow/embed_code/key/vR0XKDq4TGa77z And [https://www.elastic.co/webinars/using-rally-to-get-your-elasticsearch-cluster-size-right](https://www.elastic.co/webinars/using-rally-to-get-your-elasticsearch-cluster-size-right) ---
