Hi Everyone,

I am processing logs via logstash and this creates new dynamic indexes based on a pattern. How can i reduce the default number of shards from 5 to 3.

You can use [Index Templates](https://www.elastic.co/guide/en/elasticsearch/reference/5.5/indices-templates.html) for this.

You define a template that is set to matche your dynamic index pattern, and sets `number_of_shards` to 3
