This is a cool and underrated new feature: It basically enables simple joins of large and dynamically updated tables efficiently. This is something that has been a bit of an Achilles heel of ClickHouse, at least for me so it's exciting to see.
That said, it's not a solution for all kinds of joins, but probably covers the most common use case for most people.
