`:data-stream` shows up as index in Elasticsearch 8

[handerpeder]

Using this elasticsearch publisher config:

 {:type        :elasticsearch
  :data-stream "clj-planner"
  :url         "https://my-url"
  :http-opts   {:basic-auth ["user" "pwd"]}}

The stream shows up as an index:

As the title says I'm using Elasticsearch v8 on elastic cloud. Not sure if that is something you're supporting or not.

Hi @handerpeder,

have you set up the data-streams before pushing the data?

On the Elasticsearch website, there is a document explaining the process. https://www.elastic.co/guide/en/elasticsearch/reference/current/set-up-a-data-stream.html

I should probably clarify this in the documentation, I will add a note.

From a client perspective, there is no difference between indexing records on a data stream vs a normal index, with the only difference that in data-streams the name of the index stays the same and doesn't contain a formatted date (like: my-index-2022-06-21)

You can also convert an index alias to a data stream.
