Is there a way to push distinct values of a field from `indexA` to a new `indexB` on a regular basis(daily or monthly)?

Use Case: I want to create `indexB` from one of the fields of `indexA`, and on a daily basis do an update on this index to be used for filtering.

Welcome!

That sounds like a good candidate for the reindex API.

Thanks @dadoonet for your reply.  
I am checking out reindex API now.  
Can we do that on a regular basis directly from Kibana using a Watcher or any other service?  
like running this query each day?

IMHO that would probably be easier to run that from a cronjob.

But you can probably use a watch with a webhook: [Watcher webhook action | Elasticsearch Guide [7.12] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/actions-webhook.html)
