CDC connector

CDC source connectors capture log changes of databases (such as MySQL, MongoDB, and PostgreSQL) into Pulsar.

note

CDC source connectors are built on top of Canal and Debezium and store all data into Pulsar cluster in a persistent, replicated, and partitioned way.

Currently, Pulsar has the following CDC connectors.

Name	Java Class
Canal source connector	org.apache.pulsar.io.canal.CanalStringSource.java
Debezium source connector	org.apache.pulsar.io.debezium.DebeziumSource.java org.apache.pulsar.io.debezium.mysql.DebeziumMysqlSource.java org.apache.pulsar.io.debezium.postgres.DebeziumPostgresSource.java
