GroupByProcessor

class GroupByProcessor[P <: (Row) ⇒ Unit, K] extends (Row) ⇒ Unit

Generic row processor that groups rows based on a key function. This is higher-order processor that delegates the actual operations to sub-processors.

P

Type of sub-processors that perform the actual operations.

K

Type of group keys.
