= Camel-Kafka-connector Quartz Source 

This is an example for Camel-Kafka-connector Quartz 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-quartz-kafka-connector/0.11.5/camel-quartz-kafka-connector-0.11.5-package.tar.gz
> untar.gz camel-quartz-kafka-connector-0.11.5-package.tar.gz
----

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/quartz/quartz-source/config/CamelQuartzSourceConnector.properties`

[source]
----
name=CamelQuartzSourceConnector
connector.class=org.apache.camel.kafkaconnector.quartz.CamelQuartzSourceConnector
tasks.max=1

key.converter=org.apache.kafka.connect.storage.StringConverter
value.converter=org.apache.kafka.connect.storage.StringConverter

topics=mytopic

camel.source.path.groupName=Camel
camel.source.path.triggerName=quartz-sample
camel.source.endpoint.cron=0/5+*+*+*+*+?
----

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 Quartz Source connector:

[source]
----
$KAFKA_HOME/bin/connect-standalone.sh $KAFKA_HOME/config/connect-standalone.properties $EXAMPLES/quartz/quartz-source/config/CamelQuartzSourceConnector.properties
----

We'll get multiple message with statistics

On a different terminal run the kafkacat consumer

[source]
----
./kafkacat -b localhost:9092 -t mytopic -f 'Headers: %h: Message value: %s\n'
% Auto-selecting Consumer mode (use -P or -C to override)
% Reached end of topic quartz-topic1 [0] at offset 0
