That... would be the marketing team for you. We do spend quite a bit of our time adding stuff that I don't think I've seen anywhere else but is extremely useful for some of our biggest clients.
Market that stuff! Blog posts, list of features, service comparison - anything. For example, I know that Tableau offers in-memory storage that can help improve performance by bring data in locally and not hitting the original source. Kato mentions something about "10x performance improvement", but there's zero explanation how this is accomplished.
We have 3 different levels of storages to avoid hitting remote. Redis cache for query, storing the results on our server and letting users edit the data as well and finally front end cache with service workers.
I think I'll start writing out the feature comparisons.
