I'm not sure if I should be applying but before I do, I'm wondering what kind of novel or interesting data driven algorithms you refer to here. Are you referring to like adaptive query planners based on runtime statistics? Real-time detection of query latency spikes? Automated creation of secondary indexes based on usage patterns? Statistical smarts to decide what to cache and when? These would be sort of runofthemill for any modern database product, can you clarify if you are looking for any of these?

Asking in good faith out of genuine curiosity: I kind of associate ClickHouse with Yandex. What's the present-day relationship and legal setup, and how does it jive with Western sanctions against Russia?
