Right, relational databases only return flat tabular results but that seems minor compared to performance increase you gain. Clickhouse is fast but not as operationally friendly as the others. It's more much work once you go beyond a single node so I'd suggest looking at those other options if you want something easier to operate, or use one of the cloud data warehouses like Bigquery or Snowflake to eliminate ops entirely.
