Load representative analytical data into Databend and run the aggregations, joins, and concurrency pattern your users require. Compare result correctness and query time with the current warehouse, then measure storage and ingestion costs as data grows.
A warehouse pilot should include access control, backup or recovery, and a path to export data. Check how schema changes and late-arriving records affect reports. Decide from realistic workloads and operating effort, not a single fast benchmark query.
