If there's a list of techniques and their optimal use cases I haven't found it.
I started writing one for the day job, but then graphRAG happened, and Garnter is saying all RAG will be graphRAG.
You can't fight Gartner, no matter how wrong they are, so the work stopped, now everything is a badly implemented graph.
That's a long way to say, if there is a comparison, a link would be most appreciated
