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

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

We design relational database schemas with a complete set of solutions, but NoSQL does not. Half a year ago I read this "SQL anti-mode" book, feel very good. Just start to notice, is there an inverse pattern for nosql? A good counter pattern can be used in our design schema to tell where traps and cliffs are.
