What Is Apache Storm

Definition and Overview

Apache Storm is a distributed real-time computation system. The Apache Storm Project focuses on processing unbounded streams of data. This project offers a scalable solution for real-time analytics. Apache Storm Topology serves as the framework's backbone, enabling efficient data processing.

Historical Background

The Apache Storm Project was originally created by Nathan Marz. BackType, a startup, developed this project. Twitter later acquired BackType. The Apache Software Foundation now maintains Apache Storm. The project has evolved significantly since its inception.

Core Concepts

The Apache Storm Project relies on several core concepts. Spouts and bolts form the foundation of Storm topology. Spouts act as data sources, emitting tuples into the system. Bolts process these tuples, performing operations like filtering and aggregation. The Storm topology uses directed acyclic graphs to structure data flow. This design ensures efficient and fault-tolerant processing.

Comparison with Other Real-Time Processing Systems

Apache Storm vs. Apache Spark

Apache Storm vs Spark represents a common comparison in Big Data processing. Apache Storm excels in low-latency stream processing. Spark, on the other hand, focuses on batch processing with micro-batch capabilities. Storm topology allows for continuous data flow, while Spark processes data in intervals. Apache Storm provides real-time insights, making it ideal for time-sensitive applications.

Apache Storm vs. Flink

Apache Storm and Flink both target real-time data processing. Flink offers advanced state management and event time processing. Storm topology emphasizes simplicity and ease of use. Apache Storm Project supports multiple programming languages, enhancing flexibility. Flink's strengths lie in complex event processing and stateful computations. Apache Storm remains a popular choice for straightforward real-time tasks.

Apache Storm Architecture

Components of Apache Storm

Nimbus

Nimbus serves as the master node in the Apache Storm Architecture. Nimbus distributes tasks to worker nodes. Nimbus monitors the cluster for failures. Nimbus ensures that the system runs smoothly. Nimbus coordinates the execution of topologies.

Supervisor

Supervisors manage worker processes in the Apache Storm Architecture. Each Supervisor runs on a separate machine. Supervisors listen for work assignments from Nimbus. Supervisors ensure that tasks are executed correctly. Supervisors report the status of tasks back to Nimbus.

Worker Processes

Worker processes execute the actual data processing tasks. Each worker process runs on a Supervisor node. Worker processes handle multiple tasks simultaneously. Worker processes ensure efficient data processing. Worker processes contribute to the scalability of the Apache Storm Architecture.

Data Flow in Apache Storm

Spouts

Spouts act as data sources in the Apache Storm Architecture. Spouts emit streams of data into the system. Spouts can connect to various data sources. Spouts provide the input for further processing. Spouts ensure continuous data flow.

Bolts

Bolts process the data emitted by Spouts. Bolts perform operations like filtering and aggregation. Bolts can transform data streams in real-time. Bolts ensure that data is processed efficiently. Bolts contribute to the flexibility of the Apache Storm Architecture.
