  1. class CountDistinctUpTo extends UserDefinedAggregateFunction

    Permalink

    Counts number of distinct records, but only up to a preset amount - more efficient than an unbounded count

  2. class MapSetMerge extends UserDefinedAggregateFunction

    Permalink

    Merge maps of kind string -> set<string>

  3. class MultiArraySet[T] extends UserDefinedAggregateFunction

    Permalink

    Essentially the same as MultiSet, but gets an Array for input.
