A practical example
Example: an attribution query reads campaign_id, timestamp, and revenue from two billion events. A columnar warehouse touches only those three columns, while a row-based store would read every field of every row it scans.
What to evaluate before investing
- Confirm the warehouse stores tables columnar by default, with no per-table tuning needed for event data.
- Test compression ratios on a sample of your own event exports, not vendor demo numbers.
- Check whether scanning a narrow column set on a large table bills noticeably less than a full-table scan.
Limitations and tradeoffs
Columnar layouts are poor for transactional writes that update one row at a time, so they complement rather than replace your CRM database.
