I'm working on a project where our index settings and mappings are maintained as JSON, and I'm wondering if there's a way for the current .NET client to use these to setup our indices.
I've found older posts (example here) that make it seem like this was once possible. However, the code in these examples does not seem to work with the current client; and I haven't found much when searching the Github repository for related terms, either.
Does the feature I'm asking about no longer exist, or am I just not seeing how to access it?
