Kafka is primarily used to build real-time streaming data pipelines and applications that adapt to the data streams. It combines messaging, storage, and stream processing to allow storage and analysis of both historical and real-time data.
What is Kafka in simple words?
Kafka is an open source software which provides a framework for storing, reading and analysing streaming data. ... Kafka was originally created at LinkedIn, where it played a part in analysing the connections between their millions of professional users in order to build networks between people.
Why do we use Kafka?
Kafka was designed to deliver these distinct advantages over AMQP, JMS, etc. Kafka is highly scalable. Kafka is a distributed system, which is able to be scaled quickly and easily without incurring any downtime. Apache Kafka is able to handle many terabytes of data without incurring much at all in the way of overhead.
What services use Kafka?
Today, Kafka is used by thousands of companies including over 60% of the Fortune 100. Among these are Box, Goldman Sachs, Target, Cisco, Intuit, and more. As the trusted tool for empowering and innovating companies, Kafka allows organizations to modernize their data strategies with event streaming architecture.
What does AWS Kafka do?
Apache Kafka is an open-source, distributed streaming platform that enables you to build real-time streaming applications. ... Running your Kafka deployment on Amazon EC2 provides a high performance, scalable solution for ingesting streaming data.

Is AWS Kafka?
Learn more about Kafka on AWS
AWS also offers Amazon MSK, the most compatible, available, and secure fully managed service for Apache Kafka, enabling customers to populate data lakes, stream changes to and from databases, and power machine learning and analytics applications.
Does Amazon use Kafka?
Amazon Managed Streaming for Apache Kafka (Amazon MSK) is a fully managed service that makes it easy for you to build and run applications that use Apache Kafka to process streaming and event data.
Where should you not use Kafka?
- Kafka is an overkill when you need to process only a small amount of messages per day (up to several thousand). ...
- Kafka is a great solution for delivering messages. ...
- When you need to use a simple task queue you should use appropriate instruments. ...
- If you need a database, use a database, not Kafka.
Why Kafka is so fast?
Compression & Batching of Data: Kafka batches the data into chunks which helps in reducing the network calls and converting most of the random writes to sequential ones. It's more efficient to compress a batch of data as compared to compressing individual messages.
Does Netflix use Kafka?
Apache Kafka is an open-source streaming platform that enables the development of applications that ingest a high volume of real-time data. It was originally built by the geniuses at LinkedIn and is now used at Netflix, Pinterest and Airbnb to name a few.
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.
Is Kafka at least once?
At-least-once semantics: if the producer receives an acknowledgement (ack) from the Kafka broker and acks=all, it means that the message has been written exactly once to the Kafka topic.
Is Kafka easy to learn?
IS IT EASY? Unfortunately, it's not. For those who are new to Kafka, it can be difficult to grasp the concept of Kafka brokers, clusters, partitions, topics, and logs. You'll also need to pick up how producers and consumers store and retrieve messages on Kafka clusters.
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.
Is Kafka pull or push?
With Kafka consumers pull data from brokers. Other systems brokers push data or stream data to consumers. ... Since Kafka is pull-based, it implements aggressive batching of data. Kafka like many pull based systems implements a long poll (SQS, Kafka both do).
What is Kafka and how it works?
How does it work? Applications (producers) send messages (records) to a Kafka node (broker) and said messages are processed by other applications called consumers. Said messages get stored in a topic and consumers subscribe to the topic to receive new messages.
Why Kafka is better 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.
Does Kafka use RAM?
RAM: In most cases, Kafka can run optimally with 6 GB of RAM for heap space. For especially heavy production loads, use machines with 32 GB or more. Extra RAM will be used to bolster OS page cache and improve client throughput.
Is Pulsar better than Kafka?
Kafka provides the lowest latency (5ms at p99) at higher throughputs, while also providing strong durability and high availability*. Kafka in its default configuration is faster than Pulsar in all latency benchmarks, and it is faster up to p99.
Is Kafka a hype?
Apache Kafka is definitely more than just hype. As with any new technology, you have to manage expectations every now and then. But more and more companies are realizing that they can offer digital services that are innovative and disruptive if the right data is provided and integrated.
What is the difference between Flink and Kafka?
The biggest difference between the two systems with respect to distributed coordination is that Flink has a dedicated master node for coordination, while the Streams API relies on the Kafka broker for distributed coordination and fault tolerance, via the Kafka's consumer group protocol.
What problems 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.
Is Kinesis same as Kafka?
Kafka handles data streams in real-time (like Kinesis.) It's used to read, store, and analyze streaming data and provides organizations with valuable data insights. Uber, for example, uses Kafka for business metrics related to ridesharing trips. The big difference between Kinesis and Kafka lies in the architecture.
Why is it called Kafka?
Kafka was originally developed at LinkedIn, and was subsequently open sourced in early 2011. ... Jay Kreps chose to name the software after the author Franz Kafka because it is "a system optimized for writing", and he liked Kafka's work.
What are alternatives to Kafka?
- Apache Spark.
- Amazon Kinesis.
- Red Hat AMQ.
- Apache Storm.
- Amazon SQS.
- IBM MQ.
