Data Extractor Ants

This project is a scalable web crawler architecture that uses a master-worker model to explore web pages, manage links, and store extracted data.

Architecture Overview

Level 1: High-Level Overview

    Worker --> Hub[Central Hub]
    Hub --> DataStore[Data Store]
Loading

At the highest level, the master crawler assigns tasks to workers, and the data flows into a central hub and then into a data store.

Level 2: Detailed Components

    Master[Master Crawler] -->|Assign URLs| Worker[Worker Crawlers]
    Worker -->|Fetches Pages| WorkerProcess[Processing & Extraction]
    WorkerProcess -->|Sends Data| CentralHub[Central Hub]
    CentralHub -->|Marks Links| DataStore[Data Store]
    CentralHub -->|Spawns New Crawlers| Worker
Loading

This level shows how the master assigns URLs, workers fetch and process pages, and the central hub manages link tracking and spawning new crawlers.

Level 3: Worker Crawler Details

        ExtractLinks --> UpdateVisited[Mark Links as Visited]
        UpdateVisited --> NewLinks[Add New Links to Queue]
    end

This shows the detailed flow inside each worker crawler.

Level 3: Master Crawler Details

This focuses on the master crawler's responsibilities.

Level 3: Data Store Details
