Which is better Kafka or RabbitMQ?
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.
Can Kafka replace RabbitMQ?
The use of a standardized message protocol allows you to replace your RabbitMQ broker with any AMQP based broker. Kafka uses a custom protocol, on top of TCP/IP for communication between applications and the cluster. Kafka can't simply be removed and replaced, since its the only software implementing this protocol.
Why is Kafka better than MQ?
Apache Kafka is ideal for teams that value speed and performance highly. IBM MQ is a robust traditional message queue system, but it doesn't match the speed of Apache Kafka. Users should expect messages to take longer to complete in IBM MQ and will have a harder time using it to log events.

What problem does Kafka solve?
The problem they originally set out to solve was low-latency ingestion of large amounts of event data from the LinkedIn website and infrastructure into a lambda architecture that harnessed Hadoop and real-time event processing systems. The key was the "real-time" processing.
Why Kafka is so fast?

Can Kafka replace database?
Kafka as Query Engine and its Limitations Therefore, Kafka will not replace other databases. It is complementary. The main idea behind Kafka is to continuously process streaming data; with additional options to query stored data. Kafka is good enough as a database for some use cases.
Can Kafka pull data?
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). With the pull-based system, if a consumer falls behind, it catches up later when it can.
Does Kafka need a database?

How reliable is Kafka?
Therefore, Apache-Kafka offers strong durability and fault tolerance guarantees. Note about Leaders: At any time, only one broker can be a leader of a partition and only that leader can receive and serve data for that partition. The remaining brokers will just synchronize the data (in-sync replicas).
What happens when a Kafka broker goes down?
Kafka does not create a new replica when a broker goes down. If the offline broker was a leader, a new leader is elected from the replicas that are in-sync. ... When restarting the broker, it will try to get back in sync. Once done, whether it stays a follower or becomes the leader depends if it is the prefered replica.
Is Kafka a data lake?

Is Kafka free?
Apache Kafka® is free, and Confluent Cloud is very cheap for small use cases, about $1 a month to produce, store, and consume a GB of data.
Is Kafka an API?
The Kafka Streams API to implement stream processing applications and microservices. It provides higher-level functions to process event streams, including transformations, stateful operations like aggregations and joins, windowing, processing based on event-time, and more.
Is Kafka written in Java?
Kafka started as a project in LinkedIn and was later open-sourced to facilitate its adoption. It is written in Scala and Java, and it is part of the open-source Apache Software Foundation.
