The scalability of the system is the main reason for promoting the development of NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket that can be stuffed with anything. Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to extensive research and practice on protocols and algorithms. It is through these attempts to gradually summarize some effective database construction methods. In this article, I will focus on the distributed features of the NoSQL database ...

20.4 mapping-Merging algorithm and disk indexing program now we have to shift from theory to practice. First, we'll look at the High-order function MapReduce, and then we'll use this technique in a simple indexing engine. Here, our goal is not to be the fastest and best indexing engine in the world, but to solve the problem of real design under the relevant application scenario. The 20.4.1 mapping-merging algorithm shows us the basic idea of the mapping-merging (map-reduce) algorithm in Figure 20-2. Open a certain number of ...

Of course, the ideal goal has not yet been achieved, but the road has been plainly displayed in front of us, at least we have come close to half. First of all, the MapReduce algorithm itself comes from functional programming, so using FP's idea to build the algorithm is again ...
