How We Designed a Resilient Vector Embedding Creation System for PostgreSQL Data

The system designed by the authors is a resilient vector embedding creation system for PostgreSQL data that ensures simplicity, resilience, and high performance. The system uses a trigger to track changes in the blog table and inserts jobs into a work queue when changes are detected. An embeddings creator job then polls the work queue, creates an embedding for each row, and writes it to the database. The system is designed to be highly concurrent and performant, with measures taken to prevent duplicate entries and ensure that the system can handle failures and downtimes of the external service used to create embeddings. The system's design allows users to have control over how they embed their data and where they host their database, making it a flexible solution for various use cases.
