What is the difference between Kafka and RabbitMQ?

While RabbitMQ uses exchanges to route messages to queues, Kafka uses more of a pub/sub approach. A producer sends its messages to a specific topic. A single consumer or multiple consumers—a “consumer group”—can consume those messages.

Why Kafka is so popular?

Kafka and big data at web-scale companies Because of these performance characteristics and its scalability, Kafka is used heavily in the big data space as a reliable way to ingest and move large amounts of data very quickly.

When should I use RabbitMQ?

RabbitMQ is therefore ideal for long-running tasks or blocking tasks, allowing web servers to respond quickly to requests instead of being forced to perform computationally intensive tasks on the spot. RabbitMQ simply stores messages and passes them to consumers when ready.

What is the difference between Apache Kafka and RabbitMQ?

RabbitMQ uses a distinct, bounded data flow. Messages are created and sent by the producer and received by the consumer. Apache Kafka uses an unbounded data flow, with the key-value pairs continuously streaming to the assigned topic. RabbitMQ is best for transactional data, such as order formation and placement, and user requests.

Should I use rest or Kafka for streaming?

If the user requests for something and they wait for a response, then REST is best. Kafka (or any other streaming platform) is typically used for pipelines i.e where we have forward flow of data.

What is a kestrel queue?

Written in Scala, the Kestrel broker speaks the memcached protocol. Basically, the key becomes the queue name and the object is the message. Kestrel is very simple: queues are defined in a configuration file but you can specify, per queue, storage limits, expiration, and behavior when limits are reached.

Is ActiveMQ a good alternative to Kafka?

So, Kafka is very good fit for the requirements, stellar performance, low resource usage and nice fit with the requirements. ActiveMQ is another big player in the field with an impressive feature set. ActiveMQ is more in the RabbitMQ league than Kafka and like Kafka, it is written in Java.
