Connectors
Learn what Kafka Connect connectors are shipped with Cloudera Runtime.
Cloudera Runtime comes prepackaged with a number of Cloudera developed Kafka Connect connectors. In addition, connectors that come packaged with the version of Apache Kafka that is included in Cloudera Runtime are also available for use. Manually installing and using your own custom connectors is also possible. The following collects the connectors shipped in Cloudera Runtime.
Debezium connectors
Debezium connectors capture changes from a wide variety of databases and produce the captured changes into Kafka. Using Debezium connectors makes it possible for your applications to consume and respond to change events regardless of where the changes originated from.
| Connector | Description |
|---|---|
| Debezium Db2 Source [Technical Preview] | The Debezium Db2 Source connector captures row-level changes in Db2 database tables and transfers the changes to Kafka topics. |
| Debezium MySQL Source | The Debezium MySQL Source connector reads the binary log (binlog) of a
MySQL server, produces change events for row-level INSERT,
UPDATE, and DELETE operations, and
transfers the changes to Kafka topics. |
| Debezium Oracle Source | The Debezium Oracle Source connector captures and records row-level changes that occur in databases on an Oracle server, including tables that are added while the connector is running, and transfers the changes to Kafka topics. |
| Debezium PostgreSQL Source | The Debezium PostgreSQL Source connector captures row-level
INSERT, UPDATE, and
DELETE operations, produces change evens for each
change, and transfers the changes to Kafka topics. |
| Debezium SQL Server Source | The Debezium SQL Server Source connector captures row-level
INSERT, UPDATE, and
DELETE operations that occur in the schemas of a SQL
Server database, produces change events for each change, and transfer the
changes to Kafka topics. |
Stateless NiFi connectors
The Stateless NiFi Source and Sink connectors allow you to run NiFi dataflows within Kafka Connect. Using these connectors can grant you access to a number of NiFi features without having the need to deploy or maintain NiFi on your cluster.
Stateless NiFi connectors fall in to two categories. You have the base Stateless NiFi Source (StatelessNiFiSource) and Stateless NiFi Sink (StatelessNiFiSink) connectors. In addition, there are a number of ready-to-use connectors based on Stateless NiFi Source and Sink. These Stateless NiFi-based connectors run predefined dataflows developed by Cloudera and cover common data movement use cases.

| JMS Source | The JMS Source connector is a Stateless NiFi dataflow developed by Cloudera that is running in the Kafka Connect framework. The JMS Source Connector consumes messages from a JMS broker and transfers the message body to Kafka. |
| MQTT Source | The MQTT Source connector is a Stateless NiFi dataflow developed by Cloudera that is running in the Kafka Connect framework. The MQTT Source connector consumes messages from an MQTT broker and transfers them to Kafka. |
| SFTP Source | The SFTP Source connector is a Stateless NiFi dataflow developed by Cloudera that is running in the Kafka Connect framework. The SFTP Source connector obtains files from an SFTP server and transfers them to Kafka. |
| Syslog TCP Source | The Syslog TCP Source connector is a Stateless NiFi dataflow developed by Cloudera that is running in the Kafka Connect framework. The Syslog TCP Source connector listens on a port for syslog messages over TCP and transfers them to Kafka. |
| Syslog UDP Source | The Syslog UDP Source connector is a Stateless NiFi dataflow developed by Cloudera that is running in the Kafka Connect framework. The Syslog UDP Source connector listens on a port for syslog messages over UDP and transfers them to Kafka. |
| ADLS Sink | The ADLS Sink connector is a Stateless NiFi dataflow developed by Cloudera that is running in the Kafka connect framework. The ADLS Sink connector fetches messages from Kafka and uploads them to ADLS. |
| HDFS Stateless Sink | The HDFS Stateless Sink connector is a Stateless NiFi dataflow developed by Cloudera that is running in the Kafka Connect Framework. The HDFS Stateless Sink Connector fetches messages from Kafka and stores them in HDFS. |
| HTTP Sink | The HTTP Sink connector is a Stateless NiFi dataflow developed by Cloudera that is running in the Kafka Connect framework. The HTTP Sink connector obtains messages from a Kafka topic and transfers their content in a HTTP POST requests to a specified endpoint. |
| InfluxDB Sink | The InfluxDB Sink connector is a Stateless NiFi dataflow developed by Cloudera that is running in the Kafka Connect Framework. The InfluxDB Sink Connector fetches messages from Kafka and loads them to InfluxDB. |
| JDBC Sink | The JDBC Sink connector is a Stateless NiFi dataflow developed by Cloudera that is running in the Kafka Connect framework. The JDBC Sink connector fetches messages from Kafka and loads them into a database table. |
| Kudu Sink | The Kudu Sink connector is a Stateless NiFi dataflow developed by Cloudera that is running in the Kafka Connect framework. The Kudu Sink connector fetches messages from Kafka and loads them into a table in Kudu. |
| S3 Sink | The S3 Sink Connector is a Stateless NiFi dataflow developed by Cloudera that is running in the Kafka Connect framework. The S3 Sink connector fetches messages from Kafka and uploads them to AWS S3. |
Standard connectors
The following are either Cloudera developed connectors or connectors that come packaged with Apache Kafka.
| Connector | Description |
|---|---|
| Amazon S3 Sink |
The Amazon S3 Sink connector is Cloudera developed connector that consumes data from Kafka topics and streams the data to an S3 bucket. |
| HDFS Sink | The HDFS Sink connector is a Cloudera developed connector that transfer data from Kafka topics to files on HDFS clusters. |
| MirrorSourceConnector | The MirrorSourceConnector is a connector used internally by Streams Replication Manager (SRM). Within SRM, this connector is responsible for replicating topics between the source and target cluster. Standalone use of this connector is not recommended by Cloudera. |
| MirrorHeartbeatConnector | The MirrorHeartbeatConnector is a connector used internally by Streams Replication Manager (SRM). Within SRM, this connector is responsible for creating the heartbeats topic in the target cluster. It also periodically produces heartbeats into the heartbeats topic. Standalone use of this connector is not recommended by Cloudera. |
| MirrorCheckpointConnector | The MirrorCheckpointConnector is a connector used internally by Streams Replication Manager (SRM). Within SRM, this connector is responsible for replicating the committed group offsets between the source and target cluster. In addition, the connector is also capable of periodically applying the offsets to the consumer groups in the target cluster. Standalone use of this connector is not recommended by Cloudera. |
Example connectors (non-production)
The FileStream Source and Sink connectors are example connectors packaged with Apache Kafka. Both FileStream connectors are meant to be used to demonstrate the capabilities of Kafka Connect and are not production ready. As a result, even though these connectors are shipped with Runtime, they must be installed before they can be deployed. Prior to connector installation, the connectors are also not selectable for deployment on the SMM UI. See Installing FileStream connectors for installation steps.
| Connector | Description |
|---|---|
| FileStream Sink | The FileStream Sink connector reads data from Kafka and transfers that data to a local file. |
| FileStream Source | The FileStream Source connector reads data from a file and transfers the data to Kafka. |
