and write for the whole piece of data.1.4 Vertical Expansion VS Horizontal expansionThe biggest difference between SQL and NoSQL databases may be in scaling, and of course scaling up to support the growing demand. To support more concurrency, SQL database is scaled up, that is, it improves processing power and uses a faster computer, so that processing the same data sets is faster. Because the data is stor

The scalability of the system is the main reason for the development of the NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket, and everything can be plugged in. Although the NoSQL movement does not bring fundamental technological changes to distributed data pr

columns-based storage (Cassandra), key/value storage (memcached), and document-based storage (couchdb) and graph structure storage (neo4j) 4. Unlike traditional relational databases, which have unified SQL language operation interfaces, nosql systems usually have their own unique API interfaces. 5. In terms of architecture, you must understand that the nosql system is designed for use in clusters

In-depth analysis of distributed algorithms for NoSQL Databases System scalability is the main reason for promoting the development of NoSQL, including distributed system coordination, failover, resource management and many other features. In this case, NoSQL sounds like a big basket, and everything can be inserted. Although the

Recently I am reading nosql. A major advantage of nosql over relational databases is high availability. Therefore, some questions are raised: Why does nosql achieve high availability while relational databases suffer from criticism in this regard? Relational Database Service Oracle and sqlserver are both distr

Of course, NoSQL systems aren ' t the only context in which such things has happened in the past. A great number of people has talked about optimistic concurrency control and recovery without much of the details really Being worked out (see my discussions on this topic INNBSP;HTTP://BIT.LY/
