3  Key-Value and Blob Storage

Chapter Outline:

• 3.1. Dictionaries & Caching (db.dict)
  • A Python-like dictionary interface: config["api_key"] = ...
  • Standard methods: .get(), del, len(), iterating with .items().
  • Use Case: Caching with TTL: Using .set(key, value, ttl_seconds=3600).
• 3.2. Blob Storage (db.blobs)
  • Storing binary data (images, PDFs, files) with metadata.
  • API: .put(key, data, metadata), .get(key).
  • The Blob object: Accessing .data and .metadata.
