ClickHouse is the market leader in real-time analytics so it's an interesting take that you don't think it qualifies.

For certain definition of realtime, certainly (as would any system with bounded ingestion latency), but it’s not low-latency streaming realtime. Tens of seconds or more can pass before new data becomes visible in queries in normal operation. There’s batching, there’s merging, and its overall architecture prioritizes throughput over latency.
