I see this as a very interesting project. I use ClickHouse as OLAP and I'm very happy with it. I can tell you features that make me stick to it. If some day QuestDB offers them, I might explore the possibility to switch but never before. - very fast (I guess we're aligned here) - real time materialized views for aggregation functions (this is absolutely a killer feature that makes it quite pointless to be fast if you don't have it) - data warehouse features: I can join different data sources in one query. This allows me to join, for instance, my MySQL/MariaDB domain dB with it and produce very complete reports. - Grafana plugin - very easy to share/scale at table level - huge set of functions, from geo to URL, from ML to string manipulation - dictionaries: I can load maxdb geo dB and do real time localisation in queries I might add some more once they come to my mind. Having said this, good job!!!
