🗄️ HBase on HDInsight¶

Master HBase on HDInsight. Learn NoSQL design, real-time reads/writes, and integration patterns.

🎯 Learning Objectives¶

• Understand HBase architecture
• Design schemas for NoSQL
• Perform CRUD operations
• Optimize for performance
• Integrate with Phoenix

📋 Prerequisites¶

• HDInsight cluster with HBase
• NoSQL concepts - Row keys, column families
• Java or Python

🏗️ HBase Architecture¶

• Region Servers - Store data
• Master Server - Coordinates regions
• ZooKeeper - Distributed coordination
• HDFS - Underlying storage

📊 Schema Design¶

# Create table
create 'users', 'profile', 'activity'

# Put data
put 'users', 'user001', 'profile:name', 'John Doe'
put 'users', 'user001', 'profile:email', 'john@example.com'

# Get data
get 'users', 'user001'

# Scan
scan 'users'

🔍 Phoenix SQL Layer¶

-- Create Phoenix table
CREATE TABLE users (
    user_id VARCHAR PRIMARY KEY,
    name VARCHAR,
    email VARCHAR
);

-- Query with SQL
SELECT * FROM users WHERE name = 'John Doe';
