| = Camel-Kafka-connector Cron Source |
| |
| This is an example for Camel-Kafka-connector Cron Source |
| |
| == Standalone |
| |
| === Running Kafka |
| |
| [source] |
| ---- |
| $KAFKA_HOME/bin/zookeeper-server-start.sh $KAFKA_HOME/config/zookeeper.properties |
| $KAFKA_HOME/bin/kafka-server-start.sh $KAFKA_HOME/config/server.properties |
| $KAFKA_HOME/bin/kafka-topics.sh --create --bootstrap-server localhost:9092 --replication-factor 1 --partitions 1 --topic mytopic |
| ---- |
| |
| === Download the connector package |
| |
| Download the connector package tar.gz and extract the content to a directory. In this example we'll use `/home/oscerd/connectors/` |
| |
| [source] |
| ---- |
| > cd /home/oscerd/connectors/ |
| > wget https://repo1.maven.org/maven2/org/apache/camel/kafkaconnector/camel-cron-kafka-connector/0.11.5/camel-cron-kafka-connector-0.11.5-package.tar.gz |
| > untar.gz camel-cron-kafka-connector-0.11.5-package.tar.gz |
| ---- |
| |
| In 0.11.5, you'll need to add also camel-quartz and quartz dependency. |
| |
| [source] |
| ---- |
| > cd /home/oscerd/connectors/camel-cron-kafka-connector |
| > wget https://repo1.maven.org/maven2/org/apache/camel/camel-quartz/3.7.0/camel-quartz-3.7.0.jar |
| > wget https://repo1.maven.org/maven2/org/quartz-scheduler/quartz/2.3.2/quartz-2.3.2.jar |
| ---- |
| |
| We are now ready |
| |
| === Configuring Kafka Connect |
| |
| You'll need to set up the `plugin.path` property in your kafka |
| |
| Open the `$KAFKA_HOME/config/connect-standalone.properties` and set the `plugin.path` property to your choosen location: |
| |
| [source] |
| ---- |
| ... |
| plugin.path=/home/oscerd/connectors |
| ... |
| ---- |
| |
| === Setup the connectors |
| |
| Open the Cron configuration file at `$EXAMPLES/cron/cron-source/config/CamelCronSourceConnector.properties` |
| |
| [source] |
| ---- |
| name=CamelCronSourceConnector |
| connector.class=org.apache.camel.kafkaconnector.cron.CamelCronSourceConnector |
| tasks.max=1 |
| |
| key.converter=org.apache.kafka.connect.storage.StringConverter |
| value.converter=org.apache.kafka.connect.storage.StringConverter |
| |
| topics=cron-topic |
| |
| camel.source.endpoint.schedule=0/5+*+*+*+*+? |
| camel.source.path.name=cron-timer |
| ---- |
| |
| In this case we are using local unix socket. |
| |
| For the containerId you'll need to use the value of the running debian container. |
| |
| === Running the example |
| |
| Run the kafka connect with the Cron Source connector: |
| |
| [source] |
| ---- |
| $KAFKA_HOME/bin/connect-standalone.sh $KAFKA_HOME/config/connect-standalone.properties $EXAMPLES/cron/cron-source/config/CamelCronSourceConnector.properties |
| ---- |
| |
| We'll get multiple message with statistics |
| |
| On a different terminal run the kafkacat consumer |
| |
| [source] |
