[SPARK-4233] [SQL] UDAF Interface Refactoring #5542

chenghao-intel · 2015-04-16T18:46:27Z

This PR will keep both old / new versions of UDAF, and switch them by

SET spark.sql.aggregate2=true/false;

The new interface is

trait AggregateFunction2 {
  self: Product =>

  // Specify the BoundReference for Aggregate Buffer
  def initialize(buffers: Seq[BoundReference]): Unit

  // Initialize (reinitialize) the aggregation buffer
  def reset(buf: MutableRow): Unit

  // Get the children value from the input row, and then
  // merge it with the given aggregate buffer,
  // `seen` is the set that the value showed up, that's will
  // be useful for distinct aggregate. And it probably be
  // null for non-distinct aggregate
  def update(input: Row, buf: MutableRow, seen: JSet[Any]): Unit

  // Merge 2 aggregation buffers, and write back to the later one
  def merge(value: Row, buf: MutableRow): Unit

  // Semantically we probably don't need this, however, we need it when
  // integrating with Hive UDAF(GenericUDAF)
  @deprecated
  def terminatePartial(buf: MutableRow): Unit = {}

  // Output the final result by feeding the aggregation buffer
  def terminate(buffer: Row): Any
}
