How to write redis read and write separation code

Use Redis to implement read-write separation code, which is achieved by connecting the write server and multiple read servers: 1. The write operation is performed using the write server client; 2. The read operation is performed using the read server client; 3. Ensuring data consistency requires regular synchronization of data between the write server and the read server.

Redis read-write separation code

Implementing read-write separation in a distributed system can improve the performance and performance of the system. Scalability, the following is a code example using Redis to achieve read-write separation:

Code example:

<code class="python">import redis

# 创建 Redis 客户端，连接到写服务器
write_client = redis.Redis(host='write-host', port=6379)

# 创建 Redis 客户端，连接到读服务器
read_client = redis.Redis(host='read-host', port=6379)

# 写操作（SET）
write_client.set('key', 'value')

# 读操作（GET）
read_client.get('key')</code>

Code description:

• Create two Redis clients and connect to the write server and read server respectively.
• Use write_client for write operations (such as SET).
• Use read_client for read operations (such as GET).

Note:

• In actual applications, it is usually necessary to use a load balancer to manage access to the read server.
• Read servers should not save write requests to avoid data inconsistencies.
• Regularly synchronize the data of the write server and the read server to ensure data consistency.
