Required when method is RangeId, Random, Ntile, DataDriven or Timepartition. Should be a high-cardinality column (e.g., primary key) for even distribution. For Timepartition (0.18+) it is a tuple of a date column and time parts: '(col,year)', '(col,year,month)', '(col,year,month,day)' or '(col,year,week)'. Not needed for Ctid, Rowid, Physloc, NZDataSlice, DBPartition or None methods."

Previous value: -"Parallelism method. Ntile: even distribution on numeric key. DataDriven: distinct value partitions, works with any data type. PhysLoc/Physloc: SQL Server physical location (no key needed). Ctid: PostgreSQL physical tuple ID (no key needed). Rowid: Oracle physical ROWID (no key needed). RangeId: numeric min/max range.
