(How) can one configure multiple ElasticSearch nodes (`es_url`) in Zammad?

Infos:

  • Used Zammad version: 6.4.1-1734476180.a187f3a5.bookworm
  • Used Zammad installation type: package
  • Operating system: Debian 12 (“bookworm”)
  • Browser + version: not relevant

Problem:

We are currently using an “external” ElasticSearch cluster for Zammad. So far I could only find instructions to specify a single ElasticSearch URL for Zammad (Set Up Elasticsearch — Zammad System Documentation documentation). However that defies the purpose of having an ElasticSearch cluster. Is there a way (and how) to configure multiple es_urls? I could not find any related instructions here or elsewhere.

If there is no way right now: Are there plans to implement this possibility and is there a timeframe for the implementation?

Cheers
