Why Kafka is so fast?

Kafka relies on the filesystem for the storage and caching. The problem is disks are slower than RAM. This is because the seek-time through a disk is large compared to the time required for actually reading the data. But if you can avoid seeking, then you can achieve latencies as low as RAM in some cases.

Can Kafka replace MQ?

While IBM MQ or JMS in general is used for traditional messaging, Apache Kafka is used as streaming platform (messaging + distributed storage + processing of data). Both are built for different use cases. You can use Kafka for “traditional messaging”, but not use MQ for Kafka-specific scenarios.

Why RabbitMQ is better than Kafka?

Kafka offers much higher performance than message brokers like RabbitMQ. It uses sequential disk I/O to boost performance, making it a suitable option for implementing queues. It can achieve high throughput (millions of messages per second) with limited resources, a necessity for big data use cases.

Why do we need Kafka streams?

Kafka Streams, a client library, we use it to process and analyze data stored in Kafka. It relied on important streams processing concepts like properly distinguishing between event time and processing time, windowing support, and simple yet efficient management and real-time querying of application state.

What is Kafka not good for?

Kafka is not designed to be a task queue. There are other tools that are better for such use cases, for example, RabbitMQ. If you need a database, use a database, not Kafka. Kafka is not good for long-term storage.

Kafka is easy to set up and use, and it is easy to figure out how Kafka works.

Kafka is speedy and fault-tolerant distributed streaming platform. However, there are some situations when messages can disappear. It can happen due to misconfiguration or misunderstanding Kafka’s internals.
