# Spark Data Engineering
Welcome to the Spark Data Engineering repository! This project demonstrates the use of Apache Spark for real-time and batch data processing, providing insights into how data engineering, data analytics, and data science roles interplay within the data ecosystem.
## Overview
This repository is a hands-on guide for building scalable data pipelines using Apache Spark. It covers essential concepts such as data acquisition, transport, storage, processing, and serving, with examples of both batch and real-time data processing.
### Key Sections:
- **Data Engineer vs Data Analytics vs Data Science**
- **Data Engineer Functions**
- **Batch vs Real-Time Processing**
- **Data Engineering with Spark**
## Data Engineer vs Data Analytics vs Data Science
Data Engineering, Data Analytics, and Data Science are interconnected yet distinct roles in the data ecosystem. Here’s how they differ:
- **Data Engineers** build and maintain the infrastructure for data collection, storage, and processing.
- **Data Analysts** interpret data to provide actionable insights.
- **Data Scientists** develop predictive models and algorithms to uncover deeper insights from data.
## Data Engineer Function
### 1. Acquisition
Extract data from various sources (databases, APIs, etc.) and publish it to a data pipeline.
### 2. Data Transport
Move data within the pipeline securely and efficiently.
### 3. Data Storage
Manage data storage with a focus on latency, security, and scalability.
### 4. Data Processing
Cleanse, filter, and transform data to prepare it for analysis.
### 5. Data Serving
Make processed data available for consumption with security in mind, using pull or push models.
## Batch vs Real-Time Processing
### Batch Processing
Processes data in large volumes at scheduled intervals, ideal for tasks like reporting and data aggregation.
### Real-Time Processing
Processes data continuously as it arrives, essential for applications requiring immediate analysis and action.
## Data Engineering with Spark
Apache Spark is a powerful tool for both batch and real-time data processing. This section demonstrates how to use Spark for various data engineering tasks:
- **Data Ingestion**: Ingest data from sources like HDFS, Kafka, etc.
- **Data Transformation**: Perform complex data transformations using Spark’s API.
- **Batch Processing**: Efficiently process large datasets with Spark’s RDDs.
- **Real-Time Processing**: Utilize Spark Streaming for real-time data processing.
- **Data Storage and Serving**: Integrate with various storage systems to serve processed data.
### Benefits of Using Spark
- **Speed**: In-memory processing for faster data handling.
- **Ease of Use**: Supports multiple programming languages (Java, Scala, Python, R).
- **Scalability**: Handles large datasets with ease.
- **Unified Engine**: Supports both batch and stream processing.
## Getting Started
### Prerequisites
- **Apache Spark 3.x**
- **Java 8 or higher**
- **Scala 2.12 or higher**
- **Hadoop 3.x** (for HDFS integration)
### Installation
1. Clone the repository:
\`\`\`bash
git clone https://github.com/rishabh-agarwal/spark-data-engg.git
\`\`\`
2. Navigate to the project directory:
\`\`\`bash
cd spark-data-engg
\`\`\`
3. Set up your Spark environment and install necessary dependencies.
### Running Examples
1. **Batch Processing Example**:
- Follow the instructions in the `batch-processing/` directory to run batch processing jobs.
2. **Real-Time Processing Example**:
- Navigate to the `real-time-processing/` directory for real-time processing examples using Spark Streaming.
