Incremental data framework for AI agents
CocoIndex is an open-source incremental data framework designed to provide AI agents with continuously fresh context. It eliminates the need for re-processing entire datasets by tracking changes and updating only the affected portions, ensuring sub-second freshness at any scale. - Incremental Processing: Only re-indexes deltas, ensuring minimal processing overhead and sub-second freshness regardless of repository size. - Real-time Codebase Indexing: Maintains a live index of your codebase synchronized with every commit, providing structured context for coding and code-review agents. - Semantic Search: Enables agents to find code by meaning, patterns, and intent rather than string matches. - Call Graphs & Blast Radius Analysis: Visualizes dependencies and impact of changes before deployment, helping teams understand what a modification affects. - Global Repository View: Identifies duplicates and provides architectural insights across the entire codebase, not just individual files. - Persistent Data Pipeline: Features version tracking, caching, and lineage for reliable, explainable data transformations. - Multi-source Integration: Supports codebases, meeting notes, web APIs, file systems, databases, and more as input sources. - Python Native: Built with a Python API for easy integration and customization. CocoIndex is open-source and designed for self-hosting. It provides: - Control Plane: Manages persistent data pipelines, caching, and scheduling. - Version Tracking: Tracks changes in code, schema, and data end-to-end. - Observability: Monitors throughput, freshness, and cost metrics. - Failure Management: Implements retries, back-off strategies, and dead letter queues to ensure data integrity. The framework is optimized for low-latency, parallel processing and can scale to handle large repositories and complex data workflows. View examples | Documentation | Get started
