Yup, reading that comment all I thought was exactly what I said in another comment here, it'll work great until it doesn't, and by then you'll suffer a lot to work around it

Same with scaling, scaling ES is super easy until you realize your index sizes aren't playing nicely with sharding or something and have to start working around that.

Clickhole feels like it's targeting what most people end up using ES for. Comparing it to ES and talking about what's missing is kind of missing the point imo.
