How to work Index Template?

[Subin_Lee]

Hi there!

I'm using AWS Managed OpenSearch 2.17.

I'm just wondering how to work Index Templates of Elasticsearch.
I want to make Index Template in Dashboard of AWS OpenSearch.

If I only define 'Number of primary shards, Number of replicas', then what happen for other setting fields?

Those would follow set-up when create Index automatically?
Or, Should I put more settings for templates.

I'm new to use this tool🥲

OpenSearch/OpenDistro are AWS run products and differ from the original Elasticsearch and Kibana products that Elastic builds and maintains. You may need to contact them directly for further assistance. See What is OpenSearch and the OpenSearch Dashboard? | Elastic for more details.
