How to implement multi-tenant deployment and isolated storage of data in MySQL?

With the rapid development of cloud computing, multi-tenant architecture is becoming more and more common. In this architecture, multiple tenants can share the same application instance, but their data must be strictly isolated. As a commonly used relational database management system, MySQL provides developers with some methods to achieve multi-tenant deployment and isolated storage of data.

1. Use database instances for multi-tenant deployment

In MySQL, we can use different database instances to implement multi-tenant deployment. Each tenant has an independent database instance, which ensures that each tenant's data is completely isolated. The following is a sample code:

-- 创建数据库实例
CREATE DATABASE tenant1;
CREATE DATABASE tenant2;

-- 授予租户访问数据库实例的权限
GRANT ALL PRIVILEGES ON tenant1.* TO 'tenant1'@'localhost';
GRANT ALL PRIVILEGES ON tenant2.* TO 'tenant2'@'localhost';

In the above example, we created two database instances, tenant1 and tenant2, respectively, and assigned them corresponding permissions. In this way, each tenant can only access the database instance it owns. In actual applications, more database instances can be created as needed to meet the needs of different tenants.

2. Use table prefixes for multi-tenant isolation

Another common method is to use table prefixes to achieve multi-tenant isolation storage. In the same database instance, each tenant has its own set of tables, and different prefixes are added to the tables according to certain rules. Here is a sample code:

-- 创建表前缀
CREATE TABLE tenant1_table1 (
    ...
);

CREATE TABLE tenant1_table2 (
    ...
);

CREATE TABLE tenant2_table1 (
    ...
);

CREATE TABLE tenant2_table2 (
    ...
);

In the above example, we have created a set of tables with different table prefixes for each tenant. In this way, data of different tenants can be distinguished and isolated storage is achieved. When querying data, you should use the corresponding table prefix to limit the query scope to ensure that only the data of the current tenant is obtained.

3. Use database views for multi-tenant isolation

In addition to using table prefixes, you can also use database views to implement multi-tenant isolation storage. A database view is a virtual table based on one or more tables, which can be used like an ordinary table when querying. Here is a sample code:

-- 创建数据库视图
CREATE VIEW tenant1_view AS
SELECT *
FROM tenant1_table1
UNION ALL
SELECT *
FROM tenant1_table2;

CREATE VIEW tenant2_view AS
SELECT *
FROM tenant2_table1
UNION ALL
SELECT *
FROM tenant2_table2;

In the above example, we created a database view for each tenant separately and merged the corresponding tables into one view. In this way, each tenant only needs to query the corresponding view to obtain data without directly operating the underlying table. This not only achieves isolated storage, but also facilitates data query and management.

In summary, MySQL can implement multi-tenant deployment and isolated storage of data through different methods. Developers can choose appropriate methods to ensure data security and isolation based on specific needs. Whether using database instances, table prefixes, or database views, you can effectively implement the needs of a multi-tenant architecture.

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
