- * Extension of DefaultAsyncConsistentMap that provides a weaker read consistency

+ * <p>
+ * For read/write operations that are local to a node this map implementation provides
+ * guarantees similar to a ConsistentMap. However for read/write operations executed
+ * across multiple nodes this implementation only provides eventual consistency.
