| |
| CDC source connectors capture log changes of databases (such as MySQL, MongoDB, and PostgreSQL) into Pulsar. |
| |
| > CDC source connectors are built on top of [Canal](https://github.com/alibaba/canal) and [Debezium](https://debezium.io/) and store all data into Pulsar cluster in a persistent, replicated, and partitioned way. |
| |
| Currently, Pulsar has the following CDC connectors. |
