BufferingStore

class BufferingStore[K, V] extends MergeableStore[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 store that you don't want to constantly hit. Note that calling a get/put forces a flush on this store. Also note that the Futures returned by merge are completed only when the underlying store is finally merged.
