> I don’t want a full-text search engine that also has graphs, ML, some bizarre scripting feature, log management, etc all stapled in on top
Sure, so use something else. I do need (most all of) that at my work (plus the horizontal scaling), and there's no competition. I know we're not the only ones.
Also, there's nothing bizarre about the scripting feature. There are several options for scripting, it's very flexible, and it suits implementing custom logic when you need it.
And, I'm not saying ES is perfect! I'm saying that there's a set of use-cases that only ES (to my knowledge) can fulfil, and that's complex aggregations also involving complex full-text search, over tera/petabytes of data. Clickhouse can do aggregations, but doesn't have anything close to the search chops (again, to my knowledge).
