1. Apache Hadoop:

Apache Hadoop is an open-source framework that provides distributed storage and processing capabilities for big data. It consists of Hadoop Distributed File System (HDFS) for storing large datasets across multiple machines and MapReduce for parallel processing of data across a cluster.

Key features:

  • Distributed File System: Apache Hadoop includes the Hadoop Distributed File System (HDFS), which is designed to store and manage large volumes of data across multiple machines in a distributed environment. HDFS provides fault tolerance, data replication, and high-throughput data access.
  • Scalability: Hadoop is highly scalable and can handle petabytes of data by distributing it across a cluster of commodity hardware. It supports horizontal scaling, allowing organizations to add more nodes to the cluster as their data processing needs grow.
  • MapReduce Processing Model: Hadoop utilizes the MapReduce processing model for distributed data processing. MapReduce breaks down data processing tasks into smaller tasks that can be executed in parallel across the nodes in the cluster. It efficiently processes large datasets by distributing the workload.

2. Apache Spark:

Apache Spark is an open-source cluster computing framework that provides in-memory processing capabilities for big data analytics. It supports various programming languages and offers a high-level API for distributed data processing, including batch processing, real-time streaming, machine learning, and graph processing.

Key features:

  • Speed: Spark is known for its high-speed data processing capabilities. It performs in-memory computations, which allows it to process data much faster than traditional disk-based processing frameworks. Spark leverages distributed computing and parallelism to achieve high throughput and low latency.
  • Distributed Computing: Spark enables distributed data processing, allowing users to process large datasets across a cluster of machines. It automatically distributes data and computation across multiple nodes, taking advantage of the cluster’s resources and providing efficient scaling.
  • Data Processing APIs: Spark provides various APIs for data processing, allowing developers to choose the most suitable interface for their needs. It supports APIs in Scala, Java, Python, and R. The primary APIs in Spark are the core API for general data processing, the Spark SQL API for structured data processing, the Spark Streaming API for real-time streaming analytics, and the MLlib API for machine learning tasks.

3. Apache Flink:

Apache Flink is an open-source stream processing framework that supports both batch and real-time data processing. It provides fault-tolerant stream processing with low latency and high throughput. Flink offers support for event time processing, windowing, state management, and integration with popular message queues and storage systems.

Key features:

  • Stream Processing: Flink provides a powerful stream processing model that enables the processing of real-time data streams with low latency and high throughput. It supports event-time processing, windowing, and stateful computations on streaming data.

It supports the integration of custom components and allows developers to create their own spouts (data sources) and bolts (processing units) to meet specific processing requirements. This extensibility makes Storm highly flexible and adaptable to different use cases.

5. Apache Kafka:

Apache Kafka is a distributed streaming platform that handles high-throughput, fault-tolerant, and scalable data streams. It is commonly used for building real-time data pipelines and streaming applications. Kafka provides durable and scalable messaging, allowing applications to publish and subscribe to streams of records.

Key features:

  • Publish-Subscribe Messaging System: Kafka follows a publish-subscribe messaging pattern, where data producers (publishers) send messages to Kafka topics, and data consumers (subscribers) consume those messages from the topics. This decouples producers from consumers and allows multiple consumers to subscribe to the same topic and process data independently.
  • Distributed and Scalable Architecture: Kafka is built to handle high data throughput and supports distributed deployment across multiple nodes in a cluster. It scales horizontally by adding more brokers (nodes) to the cluster, allowing it to handle large volumes of data and high-traffic workloads.
  • Fault Tolerance and Replication: Kafka provides fault tolerance and data durability by replicating data across multiple brokers. Each topic partition can have multiple replicas, with one replica acting as the leader and others as followers. If a broker fails, Kafka automatically promotes one of the follower replicas as the new leader, ensuring continuous availability and data integrity.

6. Google BigQuery:
