The answer is no, there's nothing crazy about storing data in Kafka: it works well for this because it was designed to do it. Data in Kafka is persisted to disk, checksummed, and replicated for fault tolerance. Because messaging systems scale poorly as data accumulates beyond what fits in memory.Where is Kafka used?
Kafka is used for real-time streams of data, used to collect big data or to do real time analysis or both). Kafka is used with in-memory microservices to provide durability and it can be used to feed events to CEP (complex event streaming systems), and IOT/IFTTT style automation systems.Does Kafka require Hadoop?
Apache Kafka has become an instrumental part of the big data stack at many organizations, particularly those looking to harness fast-moving data. But Kafka doesn't run on Hadoop, which is becoming the de-facto standard for big data processing.Is Kafka a message broker?
Kafka is a message bus developed for high-ingress data replay and streams. Kafka is a durable message broker that enables applications to process, persist and re-process streamed data. Kafka has a straightforward routing approach that uses a routing key to send messages to a topic.Can Kafka run without zookeeper?

With Kafka consumers pull data from brokers. Other systems brokers push data or stream data to consumers. Messaging is usually a pull-based system (SQS, most MOM use pull).

- Step 2: Start the server.
- Step 3: Create a topic.
- Step 4: Send some messages.
- Step 5: Start a consumer.
- Step 6: Setting up a multi-broker cluster.
- Step 7: Use Kafka Connect to import/export data.
- Step 8: Use Kafka Streams to process data.
