Overview
A data ingestion pattern that transfers files from client to object storage and registers document metadata in the system database.
Description
Document Upload is the process of accepting file uploads, persisting them to object storage (MinIO/S3), and creating corresponding document metadata records. This two-phase approach (storage + registration) ensures files are durably stored before any processing begins. The upload process handles file type detection, size validation, deduplication by name within a knowledge base, and thumbnail generation for supported formats.
Usage
Use this principle after creating a knowledge base and before triggering document processing. Supports multipart file uploads with multiple files per request.
Theoretical Basis
The upload pattern follows a write-ahead strategy:
- Object storage first: Files are written to MinIO/S3 before database records are created, ensuring no orphaned metadata
- Metadata registration: Document records track file location, size, type, and processing status
- Idempotent naming: Duplicate filenames within a KB are handled via deduplication suffixes
