Solid read, good basic thinking with regards to scalability via basically prefiltering data except for the one query you need to run at runtime. It's a bit strange that the author mentions Scala as lean/fast with lots of libraries (along with JS and Go) but Java is too bulky. I'd say modern Java 8 can be used in a pretty lean manner. There's also nice and small web frameworks (Spark etc.).
