after looking at the Google BigTable architecture for a long time, Merriman and his team noticed that there is no open source database platform for this service, which might be an opportunity." "We realize that many of the existing databases do not really have the" cloud computing "feature. such as elasticity, scalability, and manageability. These features can be convenient for developers and operators, and MySQL is not fully equipped with these fea

Each set has a unique identification name in the database and can contain an infinite number

MongoDB introduction: Non-relational databases are mainly used to solve the following problems: A) High database concurrency requirements B) Demand for efficient storage and access to massive data C) high scalability and availability requirements for Databases Disadvantages: A) Database Transaction consistency requirements B) database write timeliness and read timeliness requirements

MongoDBIt is a high-performance, open-source, non-pattern document-type database developed using C ++. It is a popular nosql database, in many scenarios, it can be used to replace traditional relational databases or key/value storage methods. MongoDB uses bson as the data storage and transmission format. bson is a JSON-like binary serialization document that supports nested objects and arrays. MongoDB is si

[MongoDB] Build a mongodb sharding cluster on the windows platform (2). mongodb Cluster In the previous blog, we talked about the main principles of Mongodb sharding clusters. In this blog, we will mainly describe how to build a sharded cluster. There are two steps to configure a sharding cluster: first, start all the

database. The name MONGO comes from the word "mountains" (humongous) to emphasize the scalability and performance that MongoDB provides. MongoDB provides excellent site back-end storage for high-traffic sites that need to store data such as user reviews, blogs, or other items, because it can be quickly extended and easily implemented.Here are some of the reasons
