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

A distributed model of a NoSQL database single serverWhen a server is fully competent to work, there is no need to consider the distribution, so the deployment is simple, maintenance is much more convenient;Shard FeaturesThe various parts of the data are stored in different servers in the cluster;For example, according to the letter: the key values starting with A-G are stored on the first server, with the h-n beginning of the storage to the second ..

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

10 things you should know about NoSQL Databases Since the 1/4 century, relational databases (RDBMS) have been the mainstream database models.
