Kafka Streams unit test demonstration in Spring Cloud Stream

kafka-streams-test-utils added TopologyTestDriver, Note now kafka.version need to be kept in sync manually

Reduce unnecessary logging

Extract contants to be used in test class
Changed non used key type from Object to Bytes to use BytesSerde
Added default contructor to support JsonSerde
Added toString for better test output

KafkaStreamsWordCountApplication.WordCountProcessorApplication using TopologyTestDriver

Unified intentation

Bytes as key type

Polishing

+== What is this app?
+
+This is an example of a Spring Cloud Stream processor using Kafka Streams support.
+
+The application uses two inputs - one KStream for user-clicks and a GlobalKTable for user-regions.
+Then it joins the information from stream to table to find out total clicks per region. You could compare the this with ktable join sample.
+
+=== Running the app:
+
+Go to the root of the repository.
+
+`docker-compose up -d`
+
+`./mvnw clean package`
+
+`java -jar target/kafka-streams-global-table-join-0.0.1-SNAPSHOT.jar`
+
+`docker exec -it kafka-join /opt/kafka/bin/kafka-topics.sh --create --zookeeper zookeeper:2181 --replication-factor 1 --partitions 1 --topic user-regions`
+
+`docker exec -it kafka-join /opt/kafka/bin/kafka-console-consumer.sh --bootstrap-server 127.0.0.1:9092 --topic user-regions --key-deserializer org.apache.kafka.common.serialization.StringDeserializer --value-deserializer org.apache.kafka.common.serialization.StringDeserializer --property print.key=true --property key.separator="-"`
+
+`docker exec -it kafka-join /opt/kafka/bin/kafka-console-consumer.sh --bootstrap-server 127.0.0.1:9092 --topic output-topic --key-deserializer org.apache.kafka.common.serialization.StringDeserializer --value-deserializer org.apache.kafka.common.serialization.LongDeserializer --property print.key=true --property key.separator="-"`
+
+
+Run the stand-alone `Producers` application to generate some data and watch the output on the console consumer above.
