Warehouse Partition Key

The primary partitioning field used to split warehouse tables into logical segments.

A warehouse partition key is chosen to reduce query cost and simplify maintenance in large tables. Fields such as time, region, or transaction type may serve this role. Poorly chosen partition keys can have the opposite effect by causing unnecessary scans and uneven distribution. For that reason, partition-key selection should always consider both query patterns and data structure.
