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.

    Returns the value JUST BEFORE the merge. If it is empty, it is like a zero. the key should hold: val (k,v) = kv result = get(k) key is set to: result.map(Semigroup.plus(_, Some(v)).getOrElse(v) after this.
