Expanding clusters. Balancing leadership. PyKafka is a cluster-aware Kafka protocol client for python. The fraud detector will not be a plain consumer, though. In a previous post, I showed you how to unit test Producers. Command line client provided as default by Kafka; kafka-python; PyKafka; confluent-kafka; While these have their own set of advantages/disadvantages, we will be making use of kafka-python in this blog to achieve a simple producer and consumer setup in Kafka using python. In this Kafka Connector Example, we shall deal with a simple use case. This made the consumer quite complex since each consumer had to interact both with Kafka and negotiate a multi-step group protocol with zookeeper.

The average throughput of the consumer is 2.8MB/s. Confluent's Python Client for Apache Kafka TM. You can see the workflow below. The best way to test 2-way SSL is using Kafka console, we don’t have to write any line of code to test it.
