# Redis-Canal

A Java sample project that implements real-time synchronization of MySQL data to Redis using Canal.

## Project Overview

Redis-Canal is a Spring Boot application that demonstrates how to use Alibaba's open-source Canal middleware to monitor MySQL database changes and synchronize them in real time to Redis. This project supports real-time synchronization of INSERT, DELETE, and UPDATE operations with Redis.

## Technology Stack

- **Java** - Programming language  
- **Spring Boot** - Application framework  
- **Canal** - MySQL binlog incremental subscription and consumption component  
- **Redis** - In-memory database  
- **Jedis** - Redis Java client  

## Core Features

- **Change Data Capture**: Subscribe to MySQL binlog via Canal to capture data change events in real time  
- **INSERT Synchronization**: Automatically write new data to Redis  
- **DELETE Synchronization**: Automatically remove data from Redis upon deletion  
- **UPDATE Synchronization**: Automatically update corresponding records in Redis upon modification

└── util/

```

## Quick Start

### Prerequisites

- JDK 1.8+
- Maven 3.x
- Redis 3.x+
- MySQL 5.7+ (with binlog enabled)
- Canal Server

### Configuration

Configure the following in `src/main/resources/application.properties`:

```properties
# Redis connection settings
redis.ip=your_redis_ip
redis.port=6379
redis.password=your_password

# Canal settings
canal.server=your_canal_server_ip
```

### Startup Steps

1. Clone the project to your local machine  
2. Update the Redis and Canal connection details in the configuration file  
3. Run `mvn spring-boot:run` to start the application  
4. Perform data operations in MySQL and observe the corresponding changes in Redis  

## Usage Example

```java
// Handle INSERT operation
redisInsert(columns);

// Handle DELETE operation  
redisDelete(columns);

// Handle UPDATE operation
redisUpdate(columns);
```
