A NoSQL Framework Based on the DHT
In light of the current development of NoSQL(Non-relational database) and DHT  (Distributed Hash Table )is features, this article first proposes the adoption of B + tree as a DHT data structure, which can reduce the path length when the users find the corresponding node address, make the search length maintain the tree height and support the search of the data range. This article secondly advices to use the control node to manage and monitor DHT data distribution of NoSQL, reducing the burden of DHT routing and improving the efficiency of data search. Experimental results show that such a framework can greatly improve the routing efficiency and speed up the user access speed.
