Redis as a Vector Database
Learn to use Redis as a vector database and perform vector searches.
Register →
What you’ll learn
With Redis, you can build advanced use cases thanks to the support of the vector data type. This course introduces you to semantic search and explains its advantages over the traditional full-text search. You will understand the concepts of vector embeddings and embedding models, learn to use Redis as a vector database and perform vector searches. To complete the picture, you will comprehend how Redis represents the core component of applications integrated with Large Language Models. In addition, you will understand how Redis is well-integrated in the most popular frameworks like LangChain, LlamaIndex, or FeatureForm and service providers such as Amazon Bedrock or AzureOpenAI to leverage the vector capabilities out-of-the-box.
What you’ll build
Through the course, you will put the main concepts from the theory into practice and test the main ideas behind semantic search using the most popular programming languages: Python, Java, C#, and JavaScript. You will also run examples with Jupiter notebooks. You will start with a simple application to perform a semantic search of texts and understand how to model the data for complex applications with real data. In particular, you will implement:
- A smart recommender system with a real dataset of books
- A face recognition system leveraging vector search to spot the identity of test subjects using their face
- An AI-assisted intelligent chatbot integrated with OpenAI ChatGPT
You will define the data model using the Redis Hash and JSON data types and understand how to lay down the skeleton of such projects with a few lines of code and the most popular client libraries, including RedisVL, the native Python client library optimized to work with vectors.

Mirko Ortensi wrote his first lines of code on a Commodore 64 in Basic when he was 10 years old. It was love at first sight. Eventually he earned a degree in electronic engineering and a Masters degree in software engineering at Università Politecnica delle Marche in Italy in 2002, with a thesis about pattern recognition at UPC in Barcelona, Spain. Mirko’s career has spanned several roles in software and services businesses, encompassing development and testing, system management, and support, particularly centered around databases and distributed systems. As a senior technical enablement architect at Redis, Mirko is in charge of sharing technical knowledge about Redis’s products, services, and features.
