Key Features

Distributed Computing

Processes massive datasets across clusters with fault tolerance and parallelism.

Unified API

Supports SQL, streaming, MLlib, and GraphX under one engine with consistent APIs.

In-Memory Performance

Optimized for speed with in-memory computation and DAG execution engine.

Scalable Machine Learning

Train models on distributed data using MLlib with support for pipelines and tuning.

How It Works

Install Spark

Download Spark binaries or use package managers. Configure with Hadoop or standalone mode.

Set Up Cluster

Deploy on YARN, Mesos, Kubernetes, or cloud platforms like AWS EMR or Databricks.

Write Spark Code

Use PySpark, Scala, Java, or R to define transformations and actions on RDDs or DataFrames.

Execute Jobs

Submit jobs via CLI, notebooks, or REST API. Monitor with Spark UI and logs.

Scale & Optimize

Tune memory, partitions, and caching for performance. Use Catalyst and Tungsten optimizations.

Code Example

// Apache Spark Model Training

# PySpark example: Word count
from pyspark.sql import SparkSession

spark = SparkSession.builder.appName("WordCount").getOrCreate()
text = spark.read.text("data.txt")

words = text.selectExpr("explode(split(value, ' ')) as word")
wordCounts = words.groupBy("word").count()

wordCounts.show()

Use Cases

ETL Pipelines

Transform and clean large datasets from multiple sources with Spark SQL and DataFrames.

Real-Time Analytics

Use Spark Streaming or Structured Streaming for live dashboards and alerts.

Machine Learning at Scale

Train models on distributed data using MLlib with hyperparameter tuning.

Graph Processing

Analyze relationships and networks using GraphX for social or recommendation systems.
