It is a kind of database cluster system that expands the massive data horizontally, the data table is stored on each node of sharding, and the user can easily construct a distributed MongoDB cluster by simple configuration.The data chunking of

In MongoDB (version 3.2.9), sharding refers to the distribution of collection to different servers, where each server stores only a portion of the collection, and all of the services that serve the shards form a shard cluster. The server for the

1. Introduction of ShardsSharding (sharding) is the process of splitting data and spreading it across different machines. MongoDB supports automatic sharding, which allows the database schema to be invisible to the application. For applications, it

MongoDB Shard In MongoDB there is another cluster, that is, the Shard technology, can meet the requirements of a large number of MONGODB data volume growth. When MongoDB stores massive amounts of data, a machine may not be enough
