of time (another colleague made a turntable draw, is used MONGO), with Redis is certainly not, because to save the chat record (mom, you say QQ is not very safe, what are stored), save friends Relationship, save identity information, So can not directly use Redis, decided to use MONGO, because MONGO support index, the problem,

file size limit helps ensure that a single file does not consume too much memory and does not consume too much bandwidth during the transfer process. MongoDB provides an additional set of Api-grid FS when a single file size that needs to be stored in MongoDB exceeds the maximum file size of the MONGO db limit.2. Deep nesting of Bson documentsSince the MONGO DB 2.2 update, MongoDB supports a single file wit

Mongo server cluster configuration learning the three-part MongoDB sharding mainly refers to the process of splitting the set into small blocks and separate them on different servers. Apsaradb for MongoDB supports automatic sharding to free you from manual sharding management. Use shards in the following situations: 1. The server disk is not enough. 2. A single Mongod cannot meet the performance requirements of Data Writing. 3.

MongoDB's basic use of MongoDB features: Storing data using Bson Supports relatively rich query operations (relative to other NoSQL databases) Support Index Replica set (supports multiple instances/multiple servers running the same database) Sharding (Database horizontal scaling) Modeless (data in the same data document can be different) Easy Deployment (no password by defau

service by setting up the standby node, which can reduce the pressure on the primary node, and when the client makes a data query, the request is automatically forwarded to the standby node. This setting is called the Read Preference Modes, and the Java client provides a simple way to configure it without having to manipulate the database directly. The quorum node is a special node that does not store data by itself, and the main purpose is to decide

Mongo server cluster configuration learning secondary replica set the so-called replica set is a master-slave cluster with automatic fault recovery function. The biggest difference between master-slave replication and replica set in learning No. 1 is that the replica set does not have a fixed master node, the entire cluster structure will dynamically elect a master node. If it fails, it will be dynamically changed to other nodes, and master-slave repl
