Lots of other competitors like Apache Pinot, Apache Druid and StarRocks are fighting in that default analytics space.

StarRocks has compute/storage separation in open-source as example.
When datasets are small and can easily fit into a single node [a few terabytes], this isn't as much of an issue. Yet when datasets grow far larger, or when compute/QPS needs grow while the dataset grows slower — when either side of the equation does not scale in balanced proportion with each other — that's when this separation of compute & storage becomes vital. [Either that, or you need to find hardware servers or cloud instance types that also support this imbalance of compute & storage, which is sometimes harder to do; it also locks you into a hardware configuration that cannot dynamically scale as needs and workloads change.]
Apache Pinot also offers the same 2-tier compute/storage separation. And it also has nodes for minion [administrative] tasks. Again, these are more issues for larger scale analytical use cases.

Based on looking at the docs, I don't think so. Maybe only with HDFS. Feel free to link to a page that says otherwise.

Not only. Transactions, UPDATES, CBO, Better join optimizations.
It seems that someone is stuck in 2016, when there is no good alternatives for ClickHouse exist in open source.
