What is Kafka and why it is used?
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.

Apache Kafka is an open-source distributed event streaming platform used by thousands of companies for high-performance data pipelines, streaming analytics, data integration, and mission-critical applications.
What is meant by Kafka?
Apache Kafka is a distributed publish-subscribe messaging system that receives data from disparate source systems and makes the data available to target systems in real time. Kafka is written in Scala and Java and is often associated with real-time event stream processing for big data.

Is Kafka a database?
Apache Kafka is a database. It provides ACID guarantees and is used in hundreds of companies for mission-critical deployments. However, in many cases, Kafka is not competitive to other databases.
How does Kafka work?
Distributed means that Kafka works in a cluster, each node in the cluster is called Broker. Those brokers are just servers executing a copy of apache Kafka. So, basically, Kafka is a set of machines working together to be able to handle and process real-time infinite data.
Why is it called Kafka?
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.

RabbitMQ is an open source message broker that uses a messaging queue approach. Queues are spread across a cluster of nodes and optionally replicated, with each message only being delivered to a single consumer.
Introduction
Apache Kafka is an event streaming platform used to collect, process, store, and integrate data at scale. It has numerous use cases including distributed streaming, stream processing, data integration, and pub/sub messaging.
Why Kafka? Benefits and Use Cases
Kafka is used by over 100,000 organizations across the world and is backed by a thriving community of professional developers, who are constantly advancing the state of the art in stream processing together.
Kafka Components and Ecosystem
If all you had were brokers managing partitioned, replicated topics with an ever-growing collection of producers and consumers writing and reading events, you would actually have a pretty useful system.
What is a containerized Kafka connector?
Containerized Kafka Connect is a streamlined way to get started, and Confluent maintains a Docker base image you can use. You’ll need to add dependencies for your connectors and other components, which you can fetch from a vetted list at Confluent Hub and either bake into a new image or set it to be installed at runtime if you insist.
How to improve Kafka Connect?
Best practices like creating connectors with PUT and fetching a connector’s associated topic names programmatically can improve the administration of your Kafka Connect instance via REST. Then there are little tricks like employing jq for JSON printing and peco for interactive command output filtering that will make your REST interactions a little more sprightly. The Confluent documentation for the Connect REST API (see also the Confluent Cloud documentation when using fully managed connectors) is the best source for detailed command specifics, but an overview of the basics is a good way to begin your journey with Kafka Connect’s powerful API.
What is Kafka Connect?
Kafka Connect is the pluggable, declarative data integration framework for Kafka. It connects data sinks and sources to Kafka, letting the rest of the ecosystem do what it does so well with topics full of events. As is the case with any piece of infrastructure, there are a few essentials you’ll want to know before you sit down to use it, namely setup and configuration, deployment, error handling, troubleshooting, its API, and monitoring. Confluent Developer recently released a Kafka Connect course covering these topics, and in each of the sections below, I’d like to share something about the content of each lesson in the course.
Can you use Kafka Connect with Confluent?
If fully managed Kafka Connect in Confluent Cloud is a possibility for you, it’s the most straightforward way to accomplish your integration, as you have to manage zero infrastructure yourself. If you do prefer to self-manage Kafka Connect, then permit me to recommend using Confluent Platform. In both cases, you have extensive graphical monitoring tools that let you quickly gain an overview of your data pipelines. From the overview, you might just drill down into a list of consumers for each pipeline, and then one step deeper into their specifics—seeing real-time statistics like topic consumption information and partition offsets. If you aren’t using Confluent Cloud or Confluent Platform, your options for monitoring Kafka Connect lie in JMX metrics and REST, because your Kafka Connect instance itself exposes extensive information.
Is Kafka Connect self managed?
In this video, you’ll see Kafka with self-managed Kafka Connect in action, taking data from a MySQL source via Debezium CDC, into Kafka, and out to Elasticsearch and Neo4j from where some nice visualization is done on the data in near real time.
Is Apache Kafka a good data integration system?
But as much as Kafka does a good job as the central nervous system of your company’s data, there are so many systems that are not Kafka that you still have to talk to. Writing bespoke data integration code for each one of those systems would have you writing the same boilerplate and unextracted framework code over and over again. Which is another way of saying that if the Kafka ecosystem didn’t already have Kafka Connect, we would have to invent it.
Is data integration error prone?
Data integration is inherently error-prone, rely ing as it does on connections between things—even if Connect itself never produced a single error. Stack traces and logs will help you with most problems, but you need to know some basics before you wade in. For example, take a running connector with a failed task: if you start your troubleshooting by inspecting the task’s stack trace, then proceed to your Kafka Connect log—you will quickly get an idea of what is causing your problem. And the recently completed Kafka Improvement Proposals (KIPs) addressing dynamic log configuration in Connect as well as additional context for Connect log messages make the job quite a bit more pleasant.
What is Apache Kafka?
Apache Kafka is an open source, distributed data streaming platform that can publish, subscribe to, store, and process streams of records in real time. It is designed to handle data streams from multiple sources and deliver them to multiple consumers.
What is streaming data, and why does it matter?

Kafka Architecture – Fundamental Concepts
