What is Kafka good for?
If you’re unfamiliar with Kafka, it’s a scalable, fault-tolerant, publish-subscribe messaging system that enables you to build distributed applications and powers web-scale Internet companies such as LinkedIn, Twitter, AirBnB, and many others..
Is Kafka hard to read?
Well, Kafka certainly is not what you would call a ‘light’ read; you can easily get the feeling of ‘being lost’ while reading most of his works. Maybe that’s why you’re having a hard time appreciating Kafka. … Maybe that’s why you’re having a hard time appreciating Kafka.
Is Kafka a FIFO?
Basically Kafka divides a topic in partitions. Each partition is an ordered, immutable sequence of messages that is continually appended to. A message in a partition is identified by a sequence number called offset. The FIFO is only guarantee inside a partition.
What is the difference between ZooKeeper and Kafka?
Kafka uses Zookeeper to manage service discovery for Kafka Brokers that form the cluster. Zookeeper sends changes of the topology to Kafka, so each node in the cluster knows when a new broker joined, a Broker died, a topic was removed or a topic was added, etc.
Can I use Kafka as database?
The main idea behind Kafka is to continuously process streaming data; with additional options to query stored data. Kafka is good enough as database for some use cases. However, the query capabilities of Kafka are not good enough for some other use cases.
Does Kinesis use Kafka?
Like many of the offerings from Amazon Web Services, Amazon Kinesis software is modeled after an existing Open Source system. In this case, Kinesis is modeled after Apache Kafka. Kinesis is known to be incredibly fast, reliable and easy to operate.
Why Kafka has high throughput?
There are actually a lot of differences that make Kafka perform well including but not limited to: Maximized use of sequential disk reads and writes. Zero-copy processing of messages. Use of Linux OS page cache rather than Java heap for caching.
Why is Kafka faster than 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.
Why is zookeeper needed for Kafka?
Zookeeper keeps track of status of the Kafka cluster nodes and it also keeps track of Kafka topics, partitions etc. Zookeeper it self is allowing multiple clients to perform simultaneous reads and writes and acts as a shared configuration service within the system.
Does Netflix use Kafka?
Netflix embraces Apache Kafka® as the de-facto standard for its eventing, messaging, and stream processing needs. Kafka acts as a bridge for all point-to-point and Netflix Studio wide communications.
Can Kafka replace JMS?
Yes. It can be both. Kafka is like a queue for consumer groups, which we cover later. Basically, Kafka is a queue system per consumer group so it can do load balancing like JMS, RabbitMQ, etc.

How Kafka is fast?
Most traditional data systems use random-access memory (RAM) for data storage, as RAM provides extremely low latencies. Lets see pros and cons of using RAM. Pros: This approach makes them fast. … Kafka avoids Random Access Memory, it achieves low latency message delivery through Sequential I/O and Zero Copy Principle.
Why is Kafka so popular?
Kafka is easy to set up and use, and it is easy to figure out how Kafka works. However, the main reason Kafka is very popular is its excellent performance. … In addition, Kafka works well with systems that have data streams to process and enables those systems to aggregate, transform, and load into other stores.
How did Kafka die?
Over the course of his life, Kafka wrote hundreds of letters to family and close friends, including his father, with whom he had a strained and formal relationship. He became engaged to several women but never married. He died in 1924 at the age of 40 from tuberculosis.
Does Google use Kafka?
Google provides Pubsub and there are some fully managed Kafka versions out there that you can configure on the cloud and On-prem. Message duplication – With Kafka you will need to manage the offsets of the messages by yourself, using an external storage, such as, Apache Zookeeper.
Can we start Kafka without ZooKeeper?
You can not use kafka without zookeeper. … So zookeeper is used to elect one controller from the brokers. Zookeeper also manages the status of the brokers, which broker is alive or dead. Zookeeper also manages all the topics configuration, which topic contains which partitions etc.
Is ZooKeeper a load balancer?
AWS Elastic Load Balancing (ELB) can be classified as a tool in the “Load Balancer / Reverse Proxy” category, while Zookeeper is grouped under “Open Source Service Discovery”.
