Deep Dive into Amazon DocumentDB and Its Innovations

Overview

  • This session covers the key features and innovations introduced in Amazon DocumentDB in 2024.
  • The presenters are Cody Allen, a Specialist Solutions Architect, and Vin, a Product Manager leading DocumentDB.
  • They start with a quick refresher on the DocumentDB architecture and then dive into the new features released this year.

DocumentDB Architecture Recap

  • The key aspects of the DocumentDB architecture are:
    • Separation of compute and storage layers
    • Distributed storage volume for high availability and durability
    • Independent buffer cache for each replica instance

New Features and Innovations in 2024

  • The presenters highlight the major features released in 2024, including:
    • IAM Authentication
    • Vector Search
    • Global Cluster Improvements (Managed Failover and Managed Switchover)
    • Performance and Cost Optimizations (Document Compression)
    • Programmability Features (JSON Schema Validation)

IAM Authentication

  • Allows clients to authenticate against DocumentDB using AWS IAM credentials.
  • IAM identities are managed externally and mapped to existing DocumentDB users/roles.
  • Provides centralized authentication and visibility through CloudWatch.

Global Cluster Improvements

  • Managed Failover:
    • Promotes a secondary region to primary with minimal downtime and potential data loss.
    • Useful for business continuity events like regional outages.
  • Managed Switchover:
    • Promotes a secondary region to primary with no data loss.
    • Useful for controlled scenarios like maintenance or multi-region applications.
  • Both features maintain the global cluster topology automatically.

Performance and Cost Optimizations

  • Document Compression:
    • Reduces document size and storage requirements.
    • Improves read/write performance by reducing I/O.
    • Customizable compression threshold (down to 128 bytes) for optimal efficiency.
  • Key Size Optimization:
    • Reducing key names can significantly reduce document size.
    • Can lead to substantial savings at scale (e.g., over 1TB for 20 billion documents).

Programmability Features

  • JSON Schema Validation:
    • Allows defining validation rules for document structure and content.
    • Enforces data integrity and consistency across multiple applications.
  • Bypass Document Validation parameter:
    • Enables temporarily bypassing validation rules during development and migrations.

Conclusion

  • The presenters emphasize that the new features are a result of close collaboration with customers.
  • They encourage attendees to provide feedback and share their use cases to drive future DocumentDB innovations.
  • Additional resources are provided, including deployment optimization tools, a data modeling ebook, and a new training course.
