+# Camel-Kafka-connector AWS2 Kinesis Source
+
+This is an example for Camel-Kafka-connector AWS2-Kinesis Source
+
+## Standalone
+
+### What is needed
+
+- An AWS Kinesis stream
+- Some work on AWS console
+
+### Running Kafka
+
+```
+$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
+```
+
+=== Setting up the needed bits and running the example
+
+You'll need to setup 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
+
+You'll need to build your connector starting from an archetype:
+
+```

+```
+
+We'll need to add a little transform for this example. So import the ftp-extended project in your IDE and create a class in the only package there
+
+```
+package org.apache.camel.kafkaconnector;
+
+import java.util.Map;
+
+import org.apache.camel.kafkaconnector.utils.SchemaHelper;
+import org.apache.kafka.common.config.ConfigDef;
+import org.apache.kafka.connect.connector.ConnectRecord;
+import org.apache.kafka.connect.transforms.Transformation;
+import org.slf4j.Logger;
+import org.slf4j.LoggerFactory;
+
+import software.amazon.awssdk.services.kinesis.model.Record;
+
+public class KinesisRecordDataTransforms <R extends ConnectRecord<R>> implements Transformation<R> {
+ public static final String FIELD_KEY_CONFIG = "key";
+ public static final ConfigDef CONFIG_DEF = new ConfigDef()
+ .define(FIELD_KEY_CONFIG, ConfigDef.Type.STRING, null, ConfigDef.Importance.MEDIUM,
+ "Transforms Data to String");
+
+ private static final Logger LOG = LoggerFactory.getLogger(KinesisRecordDataTransforms.class);
+
+ @Override
+ public R apply(R r) {
+ Object value = r.value();
+
+ if (value instanceof Record) {
+ LOG.debug("Converting record from Data to String");
+ Record message = (Record) r.value();
+
+ String payload = new String(message.data().asByteArray());
+ return r.newRecord(r.topic(), r.kafkaPartition(), null, r.key(),
+ SchemaHelper.buildSchemaBuilderForType(payload), payload, r.timestamp());
+
+ } else {
+ LOG.debug("Unexpected message type: {}", r.value().getClass());
+
+ return r;
+ }
+ }
+
+ @Override
+ public ConfigDef config() {
+ return CONFIG_DEF;
+ }
+
+ @Override
+ public void close() {
+
+ }
+
+ @Override
+ public void configure(Map<String, ?> map) {
+
+ }
+}
+```
+
+On AWS console create a Kinesis stream delivery stream named streamTest.
+
+Now it's time to setup the connectors
+
+Open the AWS2 Kinesis configuration file
+
+```
+name=CamelAws2-kinesisSourceConnector
+connector.class=org.apache.camel.kafkaconnector.aws2kinesis.CamelAws2kinesisSourceConnector
+tasks.max=1
+
+key.converter=org.apache.kafka.connect.storage.StringConverter
+transforms=KinesisRecordDataTransforms
+transforms.KinesisRecordDataTransforms.type=org.apache.camel.kafkaconnector.KinesisRecordDataTransforms
+
+topics=mytopic
+camel.source.path.streamName=streamTest
+
+camel.source.endpoint.accessKey=xxxx
+camel.source.endpoint.secretKey=yyyy
+camel.source.endpoint.region=region
+```
+
+and add the correct credentials for AWS.
+
+Now you can run the example
+
+```
+$KAFKA_HOME/bin/connect-standalone.sh $KAFKA_HOME/config/connect-standalone.properties config/CamelAWS2KinesisSourceConnector.properties
+```
+
+Now send a record to Kinesis streamTest stream with 'Kinesis Event 1' as data and a second record with 'Kinesis Event 2' as data.
+
+As example you can use the KinesisComponentIntegrationTest.java from the camel main repository.
+
+On a different terminal run the consumer with kafkacat
+
+```
+./kafkacat -b localhost:9092 -t mytopic
+% Auto-selecting Consumer mode (use -P or -C to override)
+{"schema":{"type":"string","optional":false},"payload":"Kinesis Event 1."}
+{"schema":{"type":"string","optional":false},"payload":"Kinesis Event 2."}
+% Reached end of topic mytopic [0] at offset 2
+```
+
