Azure Documentdb in Practice - by Pankaj Khattar (Paperback)

Book Synopsis

Azure DocumentDB in Practice is your complete guide to understanding and leveraging Microsoft's unified document database platform, combining the power of Cosmos DB vCore with DocumentDB OSS capabilities. This book walks you through the full architecture of Azure DocumentDB, from its global foundations and MongoDB API compatibility to the vCore execution model that simplifies scaling, performance planning, and cost predictability.

Moving beyond fundamentals, you'll dive deep into performance engineering, data modeling, application development, and workload optimization tailored to Azure DocumentDB's architecture. You will then learn to benchmark and test workloads, build resilient applications using MongoDB drivers, and implement scalable, high-availability designs. Dedicated chapters on migration strategies help you transition workloads from self-hosted MongoDB, Cosmos DB RU-based models, or other databases with minimal friction. Real-world patterns, industry use cases, and reference architectures give you the blueprints needed to solve complex problems at scale. You'll learn how compute, storage, and networking layers work together, how to secure and govern your data with enterprise-grade identity and compliance features, and how to provision, size, and manage clusters for production workloads. With clear explanations, hands-on guidance, and practical best practices, this book equips you to confidently operate Azure DocumentDB in cloud-native, highly distributed environments.

Whether you're a developer, architect, or database engineer, Azure DocumentDB in Practice provides the technical depth and practical guidance required to design, build, and operate next-generation document database solutions and understand where the platform is headed next.

What You Will Learn:

• Designing and deploying production grade clusters with the right sizing, networking, and security
• How to model data effectively using optimal schema, sharding, and indexing strategies
• Diagnose and optimize performance using profiler, query plans, metrics, and best practices
• Build resilient applications using transactions, connection pooling, retry logic and Change streams
• How to run and operate clusters with backup/restore, monitoring, parameters

Who This Book Is For:

This book is meant for developers, architects, and database engineers.

About the Author

Pankaj Khattar is a Principal Engineering Manager at Microsoft and a seasoned leader in the design and evolution of large-scale distributed data systems. With over two decades of experience, he has been at the forefront of building and optimizing cloud-native database platforms that power mission-critical applications at global scale. His expertise spans database internals, distributed systems architecture, and performance engineering, with deep specialization in Azure DocumentDB, MongoDB, PostgreSQL and Big Data technologies.

At Microsoft, Pankaj has led high-impact engineering initiatives focused on pushing the boundaries of performance, scalability, and reliability in modern data platforms. He has designed and optimized distributed architectures for high-throughput systems, pioneered advanced workload modeling and benchmarking frameworks, and resolved complex production challenges in multi-node environments. His work has significantly contributed to improving query performance, concurrency handling, and resilience for enterprise-scale deployments.

Widely recognized for his ability to bridge deep system internals with real-world operational demands, Pankaj has worked closely with enterprise customers to diagnose and resolve critical issues, ranging from latency anomalies and contention hotspots to failover and data consistency challenges under stringent SLAs. His contributions have helped shape best practices for operating databases reliably at scale.

Pankaj is also an accomplished author and previously wrote Data Lake Analytics on Microsoft Azure, where he provided practical insights into building scalable data processing solutions on the cloud. He continues to contribute to the broader engineering community through mentorship, knowledge sharing, and thought leadership.

This book represents a culmination of his experience, offering not just technical depth, but a systems-level perspective on building, tuning, and troubleshooting distributed databases in real-world production environments.
