Kafka Transformation with Flink Streaming
Steps to install Zookeeper and Apache Kafka:
Step 1: Download Kafka
Download Kafka from here
Step 2: Extract downloaded file
tar -xzvf kafka-2.2.0.tgz cd kafka-2.2.0
Steps to start Zookeeper and Kafka server :
Start Kafka server:
git clone firstname.lastname@example.org:knoldus/kafka-flink-data-pipeline.g8.git cd kafka-flink-data-pipeline.g8 sbt clean compile
Execute the following command,
sbt "runMain com.knoldus.demo.KafkaProducer"
This starts producing random messages in the range 1 to 100 and push each of it into a Kafka topic queue.
Transforming the incoming messages
Step 1: Execute the following command,
sbt "runMain com.knoldus.demo.StreamDemo"
This begins Flink stream processing on the input kafka topic and transforms the messages by capitializing it and produces to a new output topic.
