NoSQL Databases

Production-grade NoSQL database patterns with MongoDB, Redis, Cassandra, and DynamoDB.

Quick Start

# MongoDB with PyMongo
from pymongo import MongoClient
from pymongo.errors import DuplicateKeyError
from datetime import datetime

client = MongoClient("mongodb://localhost:27017/")
db = client.analytics
events = db.events

# Create index for query performance
events.create_index([("user_id", 1), ("timestamp", -1)])
events.create_index([("event_type", 1)])
