ConcurrentHashMapStore

class ConcurrentHashMapStore[K, V] extends JMapStore[K, V]

A simple JMapStore whose underlying store is a Java ConcurrentHashMap useful if you are going to be modifying a store from many threads, something you in general cannot do unless the docs specifically say that a store is safe for that.
