Sync 2 indices in the same cluster

Elastic Stack Elasticsearch
1

Hello!

Is there a way to keep in sync two elasticsearch indices?
Whatever is written by the app in one index, to be copied in a second index.
It is not a viable solution to make the app writing at the same time to both indices(or to kafka).

Thanks!

As far as I know there is nothing to support this within Elasticsearch.

This is what I would have suggested. Why is this not an option?

Is that within the same cluster? Otherwise look at Cross-cluster replication | Elasticsearch Guide [8.13] | Elastic

Hello! Thank you for your answers.

It is not an option for now because it would imply pretty high additional hardware costs.

It is in the same cluster.

Thanks

So what's the use case? May be we can suggest another solution to solve this.
