You're right, this post focuses on filter queries with the WHERE clause. Aggregates are also pretty fast, a live demo is currently available with three datasets, one of them being more than 1.6 billion rows: https://demo.questdb.io/ On this you can also perform a join, in particular ASOF joins (where timestamps do not exactly match).

NB: The launch of this demo was done some time ago on HN: https://news.ycombinator.com/item?id=23616878
