BufferingMergeable

class BufferingMergeable[K, V] extends Mergeable[K, V]

A Mergeable that sits on top of another mergeable and pre-aggregates before pushing into merge/multiMerge This is very useful for cases where you have some keys that are very hot, or you have a remote mergeable that you don't want to constantly hit.
