Is NoSQL true or not? To NoSQL or not toNoSQL With the emergence of a large amount of data, NoSQL database architecture is being used by more and more people, because NoSQL architecture is more effective in big data processing. Today, when you need to store and process high-capacity data, many young developers prefer o

Label:NoSQL(NoSQL = Not Only SQL )，意即"不仅仅是SQL"。 On modern computing systems, a huge amount of data is generated every day on the network. A significant portion of this data is handled by the relational database management system (RDMBSS). The 1970 E.f.codd's paper "A Relational model of data for large shared data banks", which makes data modeling and application programming easier.The application proves that the relational model is well suited to cli

NoSQL systems generally advertise a feature, that is, good performance. Why? After so many years of development in relational databases, various optimizations have been done very deeply. NoSQL systems generally use relational database technology. What factors have bound the performance of relational databases? We can look at this problem from the perspective of system design. 1 .?

Label:MySQL is now a better nosql solution. We say this because MySQL has the advantage of performance, ease of use, and stability when storing data such as key/value (Key/value). The MySQL engine is robust and well-supported by the community and the official, with a very rich online profile covering a variety of operations, troubleshooting, replication, and various usage patterns. For this reason, MySQL has a big advantage over the emerging

At the same time, NoSQL, as a new technology in recent years, has received more and more attention. This article will be based on the DBA work of Mr. Meng Xianhao, and the relevant experience of big data operations, to share two main directions: first, the company's structure evolution on KV storage and the problems that ne

storage (disk space) is negligible. While non-relational data is stored in a flat dataset, data can often be duplicated. A single database is rarely separated, but stored as a whole, so that it is easier to read and write for the whole piece of data. Vertical Expansion vs Horizontal expansion The 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, S
