Integration of RPC services and distributed databases built using ThinkPHP6 and Swoole

Integration of RPC services and distributed databases built using ThinkPHP6 and Swoole

With the rapid development of the Internet and the continuous growth of data volume, a single database can no longer satisfy Large-scale concurrency requirements. In order to improve the throughput and scalability of the system, distributed databases have become a choice that cannot be ignored.

In the case of a distributed database, how to perform database read and write operations has become a challenge. In traditional application architecture, we usually use middleware to split the database and perform read and write operations through the ORM (Object Relational Mapping) framework. However, this approach performs poorly in high-concurrency scenarios.

In this article, we will introduce how to use ThinkPHP6 and Swoole to build an RPC (Remote Procedure Call) service and integrate it with a distributed database. By writing database operations to RPC services, we can achieve high-performance database read and write operations.

First, we need to install and configure the Swoole extension in ThinkPHP6. Swoole can be installed through Composer:

composer require swoole/swoole

Next, we can create an RPC service to handle database operations. In ThinkPHP6, we can achieve this by creating a controller.

namespace apppccontroller;

use thinkswooleRpcServer;

class Database
{
    public function select($param)
    {
        // 查询逻辑
    }

    public function insert($param)
    {
        // 插入逻辑
    }

    public function update($param)
    {
        // 更新逻辑
    }

    public function delete($param)
    {
        // 删除逻辑
    }
}

In this example, we create a Database controller and define operation methods such as select, insert, update, and delete. These methods will implement specific database read and write operation logic.

Next, we need to create an entry file for the RPC service. Create an rpc.php file in the project root directory with the following content:

use thinkswooleServer;

require __DIR__ . '/vendor/autoload.php';

Server::run([
    'host' => '0.0.0.0',
    'port' => 9501,
    'worker_num' => 4,
    'document_root' => __DIR__ . '/public',
    'enable_static_handler' => true,
    'pid_file' => __DIR__ . '/runtime/swoole.pid',
    'log_file' => __DIR__ . '/runtime/swoole.log',
    'handle' => function ($request, $response) {
        if ($request->server['path_info'] == '/rpc') {
            // 处理RPC请求
            $server = new RpcServer();
            $server->controller('apppccontrollerDatabase');
            $response->header('Content-Type', 'application/json');
            $response->end($server->execute($request->rawContent()));
        } else {
            // 处理静态资源请求
            $response->end();
        }
    },
]);

In this entry file, we use the thinkswooleServer class to create a Swoole HTTP server. We handle the request through the handle method. If the request path is /rpc, the method of the Database controller will be called to process the RPC request; if the request is for a static resource, the static resource will be returned directly.

Finally, we need to configure routing in the Swoole server. Create an rpc.php file in the project root directory with the following content:

use thinkacadeRoute;

Route::get('/', 'rpc/Router/index');

In this routing file, we map the root path / to the index method under the rpc/Router controller.

After the configuration is completed, you can use the following command to start the Swoole server:

php rpc.php

Now, we have completed the establishment and configuration of the RPC service. When a request is sent to the Swoole server, the corresponding RPC method will be automatically called to handle database read and write operations.

To sum up, the integration of RPC services built using ThinkPHP6 and Swoole and distributed databases can provide us with high-performance and scalable database reading and writing. By writing database operations into RPC services, we can reduce the load on the database and achieve high-performance read and write operations in high-concurrency scenarios.
