I'm Dave, a Data Scientist turned AI Engineer and founder of Datalumina®. On this channel, I share practical tutorials to help you become better at building data + AI applications. If you want to know how I help data professionals beyond these videos, then check out the links on my channel. 📌 Description In this video, I discuss the challenges of traditional vector databases and introduce Timescale's Pgai solution, which simplifies embedding creation and synchronization within PostgreSQL. I walk through the setup process using tools like Docker and the OpenAI API, and explain how to structure your database for both source and embedding data. Viewers will learn to automate embeddings, perform semantic searches with SQL, and utilize multiple embedding models. This integrated approach streamlines AI workflows and optimizes the use of databases like Postgres for future AI projects. #pgai #timescale #rag
