<p>The CDC Source connector is used to capture change log of existing databases like MySQL, MongoDB, PostgreSQL into Pulsar.</p>
<p>The CDC Source connector is built on top of <a href="https://debezium.io/">Debezium</a> and <a href="https://github.com/alibaba/canal">Canal</a>. This connector stores all data into Pulsar Cluster in a persistent, replicated and partitioned way.
This CDC Source are tested by using MySQL, and you could get more information regarding how it works at <a href="https://debezium.io/docs/connectors/mysql/">this debezium link</a> or <a href="https://github.com/alibaba/canal/wiki">this canal link</a>.
Regarding how Debezium works, please reference to <a href="https://debezium.io/docs/tutorial/">Debezium tutorial</a>. Regarding how Canal works, please reference to <a href="https://github.com/alibaba/canal/wiki">Canal tutorial</a>. It is recommended that you go through this tutorial first.</p>
