# 一个简单Connector的实现

## 一个简单Connector的实现

下面以MySql Connector为例,如何实现一个Source Connector

首先MySql Connector要获取到连接数据库相关的配置信息，如ip，port，账号密码，同时返回TaskClass，TaskConfig信息，MySqlTask解析MySql binlog的方法通过数据变更，缓存到BlockingQueue中,Runtime通过Task poll方法拉去BlockingQueue中数据发送到RocketMQ中。

## 运行Connector流程

调用Runtime的创建Connector的RESTful接口，启动MySql Connector，启动Task。Runtime通过poll方法拉去数据发送到broker，发送成功以后会更新binlog消费进度，并且同步到集群中其他节点，所以一个节点挂掉不会影响，其他节点接管任务不会影响进度
