Why it matters
Understanding columnar database matters because leaders need a shared, source-backed meaning before they can compare results, explain performance, or decide what to do next. Pluvo lands synced data in a columnar warehouse, the storage shape that makes the aggregations its semantic layer runs fast and reproducible.
In practice
