The three big data stores hadoop, spark, and kafka have different features and use cases. In this video we compare these three big data platforms and discover how they benefit each other and what their strengths are.
what is hadoop?
Hadoop is a framework for storing and analyzing data sets using clusters of computers. Hadoop was first released in 2007 as open-source software developed at Yahoo! and designed for Big Data processing. In 2013, Apache began sponsoring Hadoop’s project management and community development. Google, Facebook, LinkedIn, and many others use Hadoop for big data analysis.

what is the spark?
Spark is a cloud-based platform designed for the cannabis industry. Spark connects growers to brands and consumers. We believe that everyone should have access to clean, safe, and consistent cannabis. Our mission is to provide transparency about products and services while helping both sides reduce operating costs and increase profits. By connecting them, we help companies build trust with their customers while giving patients access to high-quality cannabis at affordable prices.

what is Kafka?
Kafka Technology is a way of thinking about how information flows through systems. It’s a method of looking at problems from the perspective of data flow. Kafka technology helps us think about our systems, processes and workflows in terms of data flowing through them. In essence, we treat our business as a giant stream of data. We look at each step in the system as a point where data enters, moves through and exits the system.

Hadoop vs Spark vs Kafka
Spark and Hadoop are two different technologies and both have their own advantages and disadvantages.
Kafka is a messaging system based on the message queue pattern. It was developed by LinkedIn engineer Yan Zhu. It is highly scalable and fault-tolerant. Kafka uses the concept of topics to send messages. Topics provide a way to group related messages together. A topic is a logical unit of discussion. You can create many topics and assign each topic to a particular user, organization, application, etc. to learn more about international-esim-card-vs-traditional-sim-cards
Advantages of Hadoop and Spark and Kafka Technology
Hadoop is a distributed computing framework for large-scale data processing applications. It uses clusters of commodity hardware running Linux operating systems to provide fault tolerance and horizontal scalability for big data analytics. Apache Spark is a fast and general engine for machine learning and analytics in Hadoop and beyond. Spark provides high-performance streaming analytics and SQL queries over massive datasets stored across many machines. Apache Kafka is a messaging system that stores messages (e.g., data) in topics. Kafka offers reliable message storage and makes it easy to produce and consume messages.
Benefits of hadoop and spark and kafka technology
- Hadoop/Spark/Kafka
Hadoop is a distributed processing framework designed to run applications across clusters of commodity hardware. Spark is a toolkit based on Hadoop that provides a unified programming model for data-parallel computation. Kafka is a messaging system that supports real-time applications.
Kafka can be thought of as a general purpose streaming platform. It is not related to any particular application domain. However, Kafka does have some specific use cases where it shines. One of these is the event sourcing pattern. Event stream processing is a way of capturing real time events. Examples of using event streams include stock market trading systems, IoT devices, social networks, etc. Another example would be when a user interacts with a website and then the information about their interaction is stored as an event in a database. You could then query this database to find out what happened last week, last month, etc.
- Hadoop/spark/kafka can handle big data because they have memory management issues.

- Hadoop/Big Data is scalable.
- Hadoop/big data can be deployed in a cloud environment.
- Hadoop/DataStream can be deployed on Kubernetes.
- Spark/Kafka can be deployed on Kubernets.
- Spark/streaming is scalable.
- Spark/streaming can be deployed on Kubertnets.
- Spark/streaming/kafka can be deployed in kubernetes.
- Spark/streaming and Kafka can be deployed in Kubernetes.
Hadoop Streaming
Spark is a fast analytics engine built around distributed datasets (RDDs) that provides unified programming abstraction over various back-ends, including Hadoop Distributed File System (HDFS). Kafka is a reliable message broker based on the publish/subscribe messaging pattern.All these technologies are different from each other, but they share some similarities.
Spark Streaming
Spark Streaming is a streaming processing library that integrates with Spark. It enables real-time analysis of data streams without having to collect them first. Data streams are continuous, potentially unbounded sequences of data items emitted continuously. For example, a user may enter their credit card information on a website, resulting in a stream of events. Spark Streaming processes each event as it arrives, applying transformations as necessary, and then outputting results as soon as possible.
Kafka Streams
It consists of two components: producer and consumer. Kafka Streams are a set of tools to build applications using Kafka topics and Kafka connectors. These tools enable developers to easily create complex data pipelines that process incoming messages, transform them, persist them, and finally output the transformed results to a sink.
spark vs kafka
The spark is the idea of making something happen. Kafka is the guy who does the actual work. You may have heard the term before, but what exactly is the difference between them? In the context of writing, they both mean the same thing. If someone says that they want to write a book, then they are saying that they want to make something happen, they want to start doing things. But if they say they want to write a novel, it’s not really clear what they want to achieve. So in this case, the author wants to write a story; he doesn’t know how yet, but he knows he’s going to do it. He might write a few chapters here and there, but he has no intention of publishing anything until he writes enough material to fill a complete novel. Then he’ll publish it. That’s the spark.
hadoop vs kafka
Hadoop is a software framework for distributed computing consisting of two parts: Hadoop Distributed File System (HDFS) and MapReduce. HDFS is a file system based on the client/server model using a collection of commodity servers called NameNodes. Each server stores data on behalf of clients provides access to the data and performs administrative tasks.
Kafka is a messaging platform designed to handle high volume and throughput of messages. Kafka brokers provide a reliable mechanism for sending messages between producers and consumers. It uses a publish-subscribe approach rather than request-reply.
summary
Kafka is a distributed streaming platform that supports real-time data processing. Kafka enables users to add processors to receive new data streams as they happen and process them later on. Once the data is fully processed it is stored back into KafkaWith Spark, users can work with structured data in ways similar to SQL databases. Users can query data sets and build aggregations using operations like filtering, counting, joining, and grouping. Spark’s core abstraction is RDDs (Resilient Distributed Datasets). A resilient distributed dataset is simply a collection of data items partitioned across nodes in a cluster.
