 **Canal** is a high performance data synchronization system based on MySQL binary log. Canal is widely used in Alibaba group (including [https://www.taobao.com](https://www.taobao.com/)) to provide reliable low latency incremental data pipeline.
 
 **Canal Server** is capable of parsing MySQL binlog and subscribe to the data change, while **Canal Client** can be implemented to broadcast the change to anywhere, e.g. database and [Apache Kafka](https://kafka.apache.org/).
