PostgreSQL is widely recognized for its extensibility, but can we really build a NoSQL engine on top of it? In this session, we'll explore how DocumentDB repurposes PostgreSQL's storage engine, query planner, and extension system to support MongoDB wire protocol, dynamic schemas, and document-based operations.

You will learn:

• Understand how PostgreSQL's extensibility enables the development of NoSQL features
• Explore DocumentDB's architecture
• The tradeoffs of building a NoSQL engine on top of PostgreSQL
