In MongoDB (version 3.2.9), the distribution of data refers to splitting the collection data into chunks (chunk) and distributing them on different shards (shard). There are 2 main ways to distribute data: Balanced distribution based on the number of blocks (chunk) and directed distribution based on the Slice key range

Traditional relational databases are generally composed of three levels of databases (database), tables (table), records (record), and MongoDB are made up of three levels (db), Collections (collection), document objects (documents). MongoDB for tables in relational databases, but there is no column, row, and relationship concept in the collection, which embodies the characteristics of pattern freedom.

The river is a singleton pattern on the cluster, it is automatically assigned to a node, and when the node is hung, the river is automatically assigned to another node. Currently supported data sources include: Wikipedia,
How to design a MongoDB Data Model
Effective data models serve applications. The key issue in the design architecture is whether the document model is applicable to embedded models or references ).

NoSQL databases such as MongoDB have the advantages of scalability and high performance, but the computational power is weaker than traditional SQL, such as MongoDB's grouping result is not too large, and does not directly support join operations, and the calculation engine built in the integrated report can just add to this point, Gain the advantages of MongoDB while also having strong computing power.We u
