But it is because of these problems that NoSQL was born. NoSQL has these advantages: large

, adding fields is simply a nightmare.highly Available , NoSQL can easily implement a highly available architecture without compromising performance. For example, MongoDB can quickly configure a highly available configuration with MONGOs, MONGO shards.In a NoSQL database, most queries are the way key-value pairs (key, value) are. MongoDB is a product between relational and non-relational databases, most lik

In fact, the indexes in MongoDB are similar to relational databases. They are designed to improve the efficiency of query and sorting, and the Implementation Principles are basically the same. The keys (fields) in the set can be common data types or subdocuments. MongoDB can create indexes on various types of keys. The following describes how to create, query, and maintain various types of indexes. I. Creat

The indexes in MongoDB are similar to relational databases, all in order to improve the efficiency of query and sorting, and the principle of implementation is basically consistent. Because the key (field) in the collection can be a normal data type, it can also be a subdocument. MongoDB can create indexes on various types of keys. The following sections explain the creation of various types of indexes, que

Use MongoDB in Python applications and mongodb in python applications Python is a powerful programming language used in many different types of applications in the development community. Many people know that it is a flexible language that can process almost any task. Therefore, what kind of database is needed in the Python application as flexible as the language itself? That is NoSQL, such as MongoDB.Https

MongoDB-based file server Recently, I complained about the company's file server. The existing file server saves the files to the server hard disk through the interface provided by the server and divides the files by ID. After regular backup to other servers, an accident occurred so long that the hard disk was formatted by a colleague, leading to the loss of some data. Therefore, if we re-design the file server, we will consider using
