Streaming Cassandra into Kafka

Yelp has built a robust stream processing ecosystem called Data Pipeline. As part of this system we created a Cassandra Source Connector, which streams data updates made to Cassandra into Kafka in real time. We use Cassandra CDC and leverage the stateful stream processing of Apache Flink to produce a Kafka stream containing the full content of each modified row, as well as its previous value.
