Can I create Elasticsearch cluster without replication? Which all settings needed to be taken care of, if I want to use it only for scaling and not for high availability.

Hi Abhishek,

Create index with 0 replica shards, you can define it in index mappings or index settings.  
Refer: [Index modules | Elasticsearch Guide [7.13] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/index-modules.html)

Cheers!
