CocoIndex: Open-Source Data Indexing Engine Simplifies Data Processing
CocoIndex is the world's first open-source engine supporting custom transformation logic and incremental updates, specialized for data indexing. Users declare transformations; CocoIndex creates and maintains an index, keeping the derived index up-to-date with minimal computation upon source updates. Documentation, a quick start guide, and video tutorials are available. It supports Python library installation and launching a Postgres database using Docker Compose. Users easily index data by defining indexing flows, such as splitting text into chunks, embedding them into vectors, and exporting to a vector index. Examples and demos are provided, and community contributions—code improvements, documentation updates, issue reports, feature requests, and Discord discussions—are welcome.
