Workflow Name
Vector DB Loader from Google Drive
Key Features and Highlights
This workflow automatically searches for and downloads files from a specified Google Drive folder. It supports content extraction from PDF, plain text, and JSON formats. Leveraging OpenAI’s text embedding model, it converts textual content into vector representations, which are then stored in a PGVector vector database within Postgres for efficient document vectorization management. Processed files are automatically moved to another designated folder to ensure clear and orderly file management. The workflow supports both manual triggering and scheduled automatic execution, significantly enhancing automation and operational efficiency.
Core Problems Addressed
- Automated batch processing of multiple file formats (PDF, text, JSON)
- Transforming unstructured document content into structured vector data for subsequent similarity search and knowledge base construction
- Automated file downloading, processing, and archiving to reduce manual operations and minimize the risk of omissions
- Integration of OpenAI’s powerful text embedding capabilities to achieve high-quality text vectorization
Application Scenarios
- Enterprise knowledge base construction and maintenance
- Vectorized storage and rapid retrieval of research materials
- Intelligent document analysis and content recommendation systems
- Automated document processing and archival management
- Scenarios requiring conversion of large volumes of Google Drive documents into a vector database
Main Workflow Steps
- Trigger the workflow manually or via scheduled timing
- Search for target files in the specified Google Drive folder
- Download files one by one in a loop
- Route processing based on file type via a Switch node:
- Extract text content from PDF files
- Directly extract content from plain text files
- Parse content from JSON files
- Generate text vectors using OpenAI’s text-embedding-3-small model
- Insert vector data into the designated table and collection in the Postgres PGVector database
- After processing, automatically move files to the “vectorized” archive folder in Google Drive
- Await the next trigger to repeat the process
Involved Systems or Services
- Google Drive (file search, download, move)
- OpenAI (text embedding model)
- Postgres database (PGVector vector storage)
