Apache Kafka in Action
A JDBC source connector is a Kafka Connect connector that reads records from relational databases through JDBC and publishes them to Kafka.
- How it is used
- Moves relational-table records into Kafka topics for downstream streaming use.
- How deep it goes
- Demonstrates setup, configuration, REST deployment, polling modes, update limitations, and error-handling trade-offs.
- Examples
- Uses a SQLite customers table, sample customer rows, the sqlite_customers topic, JSON configuration, and console consumer output.
- What you can do after
- Operate and configure a JDBC source connector that publishes selected database tables while recognizing polling correctness limits.

Kafka for Architects
JDBC Source Connector is a Kafka Connect connector implementation that reads records from relational databases through JDBC and publishes them to Kafka.
- How it is used
- Deploys configuration-driven pipelines that move relational database records into Kafka through Kafka Connect.
- How deep it goes
- Explains table mapping, task distribution, schema changes, polling modes, joins, and tracking trade-offs without detailing connector internals.
- Examples
- Uses bulk, incrementing, timestamp, combined, and query polling alongside an immutable transactions ODS configuration.
- What you can do after
- Operate/configure a JDBC source connector through Kafka Connect for database-to-topic replication without custom producer code.
