构建自己的连接器
任何人都可以基于公开的
Connector API
创建自己的连接器。事实上，人们
创建了各种连接器，然后把它们发布到连接器中心（
Connector Hub
），并告
诉我们怎么使用它们。如果你在连接器中心找不到可以适配你要集成的数据
存储系统的连接器，可以开发自己的连接器。你也可以把自己的连接器贡献
给社区，让更多的人知道和使用它们。关于构建连接器的更多细节已经超
出了本章的讨论范围，不过可以参考官方文档学习如何构建连接器（
http://
docs.confluent.io/3.0.1/connect/devguide.html
）。我们也建议将已有的连接器
作为入门参考，或者从使用
maven archtype
（
https://github.com/jcustenborder/
kafka-connect-archtype
）开始。另外，可以在
Kafka
的社区邮件组（
users@
kafka.apache.org
）寻求帮助，或者在邮件组里展示自己的连接器。

转化器
是如何处理数据的——转换器把

的数据行转
成
JSON
记录，然后由连接器将它们写入
Kafka
。
现在让我们深入理解每一个组件，以及它们之间是如何进行交互的。
