I am working on adding a new feature in Opensearch which can be used to disable the _recovery_source. As this is a new feature documentation needs to be added.

What other resources are available? Provide links to related issues, POCs, steps for testing, etc.

Hi @navneet1v , what is the ETA for the doc PR? Thanks!

[navneet1v]

@hdhalter I am trying to figure out where to put the documentation. There is no documentation page for metadata fields just like this:https://www.elastic.co/guide/en/elasticsearch/reference/7.17/mapping-fields.html Please suggest where to put information related to metadata fields.

Hi @navneet1v, you're right, it doesn't exist yet, but it is in progress: #6933. We may be able to finalize this content before the release so we can add it here, but I'll need to check with the author. @vagimeli - thoughts?
