精通NoSQL的进来看看这种情况有什么好的解决方案?该怎么处理
精通NoSQL的进来看看这种情况有什么好的解决方案?
网站A的数据库里有一个非常简单的表xx,字段:
id:自增
key:值是惟一的字符
value:值是任意字符串
网站B每天需要读取这个网站A里的xx表的数据。
我现在的做法是:
每当网站A操作xx表时,会同步往远程服务器C里的mysql数据库做同样的操作。这样网站B每天就从远程服务器C读取数据,供查询显示。但是这种方法的性能仍然是个问题,查询时需要连接远程服务器C里的mysql数据库,虽然网站B在查询获取数据后在本地做了缓存,但是我感觉还是不够满意。
最近发现NoSQL应该比较适合存储我的这个xx表,所以如果用NoSQL的话应该怎么操作比较好呢?
我还想到一个方法:
当网站A操作xx表时,每插入新的记录或者修改记录,会在某个目录下面专门为每条记录生成对应的一个txt文件,文件名就是key,文件内容是value。这样网站B每次查询数据时,curl网站a目录下有没有对应的txt文件名,如果有,就显示值。这个方法的缺点是会在网站A的某个目录下面生成数量非常多的小文件。
或者,有没有什么好的方法将xx表里的数据保存到一个文件中?然后传给网站B呢?然后网站B在本地查询等操作。缺点是每次网站xx表有更新等操作,需要将这个文件同步传到网站B那边去。

一,mysql主从,这是最简单的引流数据到线下和备份的方法。
二,谈谈楼主的想法:
1,所有数据主动同步给B是要花钱买流量的,想必你没有那么多闲置资金专门买无用的流量。
2,楼主没有描述机房部署情况,同机房不需要考虑带宽问题,只需要考虑磁盘和请求量。
楼主最好描述描述机房部署和每个服务器的使用目的细节吧。

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

The process of starting MySQL in Docker consists of the following steps: Pull the MySQL image to create and start the container, set the root user password, and map the port verification connection Create the database and the user grants all permissions to the database

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.

I encountered a tricky problem when developing a small application: the need to quickly integrate a lightweight database operation library. After trying multiple libraries, I found that they either have too much functionality or are not very compatible. Eventually, I found minii/db, a simplified version based on Yii2 that solved my problem perfectly.

Article summary: This article provides detailed step-by-step instructions to guide readers on how to easily install the Laravel framework. Laravel is a powerful PHP framework that speeds up the development process of web applications. This tutorial covers the installation process from system requirements to configuring databases and setting up routing. By following these steps, readers can quickly and efficiently lay a solid foundation for their Laravel project.

MySQL and phpMyAdmin are powerful database management tools. 1) MySQL is used to create databases and tables, and to execute DML and SQL queries. 2) phpMyAdmin provides an intuitive interface for database management, table structure management, data operations and user permission management.

MySQL is suitable for web applications and content management systems and is popular for its open source, high performance and ease of use. 1) Compared with PostgreSQL, MySQL performs better in simple queries and high concurrent read operations. 2) Compared with Oracle, MySQL is more popular among small and medium-sized enterprises because of its open source and low cost. 3) Compared with Microsoft SQL Server, MySQL is more suitable for cross-platform applications. 4) Unlike MongoDB, MySQL is more suitable for structured data and transaction processing.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.
