Amazon DocumentDB Installation and Usage

Amazon DocumentDB is a serverless database service based on MongoDB, providing functionality and performance similar to self hosted MongoDB. The following is a detailed introduction to installing and using Amazon DocumentDB, as well as examples of inserting, modifying, querying, and deleting data. Install Amazon DocumentDB: 1. Log in to the AWS console and open the console page of Amazon DocumentDB. On the console page, click the "Create Cluster" button. On the Create Cluster page, fill in the name, description, and other related parameters of the cluster. Select appropriate instance specifications, storage capacity, and replication options. 4. Configure network and security group rules so that Amazon DocumentDB can be accessed through the VPC and security group you specify. 5. Click on the "Create Cluster" button. Wait for the cluster creation to complete. Create a data table, insert, modify, query, and delete data: 1. Use the Mongo shell or any favorite MongoDB client to connect to the Amazon DocumentDB cluster. 2. Create a new database and collection: use mydb db.createCollection("mycollection") 3. Insert data: db.mycollection.insertOne({ name: "John", age: 30, city: "New York" }) 4. Update data: db.mycollection.updateOne({ name: "John" }, { $set: { age: 35 } }) 5. Query data: db.mycollection.find({ city: "New York" }) 6. Delete data: db.mycollection.deleteOne({ name: "John" }) Please note that in the above example, "mydb" is the database name and "mycollection" is the collection name, which you can change according to your own needs. Using Amazon DocumentDB to store and query data can be achieved through standard MongoDB query syntax. The specific query statements and operations depend on your actual needs, and can be further studied and explored based on official documents and reference materials. Precautions: -Before using Amazon DocumentDB, please ensure that you have some basic knowledge and experience in using MongoDB. -Please note some differences and limitations between Amazon DocumentDB and self hosted MongoDB, such as not supporting certain MongoDB specific operations and functions. Please refer to the official documentation for detailed information. Through the above steps, you can successfully install and use Amazon DocumentDB, and perform data table creation, data insertion, modification, query, and deletion operations.
