I have setup aws elasticsearch where a new index is created everyday, when i see the index using \_cat api i see two different size of index that are store.size(7.8) pri.store.size(3.8), I think this is happening because no of replicas is set to 1 in index setting. How can i set it to 0 permanently for all the indices ?
someone please help.

just a word if warning: this means, you are increasing the risk of dataloss, as there . is no copy of your data available within your cluster anymore.
You could create an [index template](https://www.elastic.co/guide/en/elasticsearch/reference/7.3/indices-templates.html) that sets the number of replicas, which automatically applies for the indices that match the pattern.
you can also change the number of replicas for existing indices, see [https://www.elastic.co/guide/en/elasticsearch/reference/7.3/indices-update-settings.html](https://www.elastic.co/guide/en/elasticsearch/reference/7.3/indices-update-settings.html)
