// cómo funciona

Cómo funciona

  1. Identify the context your agent needs

    Pick a source (a docs folder, a codebase, Slack, meeting transcripts) and the target it should feed, such as a pgvector table for RAG.

  2. Install CocoIndex

    Add the Python package to your project with pip.

  3. Declare the pipeline

    Write a small Python flow: walk the source, split and embed content, and declare rows and a vector index in the target - the quickstart example is about twenty lines.

  4. Run it, then re-run freely

    Run the app once to backfill; run it again any time (or continuously) and only changed files re-embed, keeping the index fresh at a fraction of the cost.

// características

Por qué gusta tanto

Delta-only incremental processing

Only the change - in source data or in your transformation code - is reprocessed; unchanged content hits the cache, so freshness costs a fraction of full recomputation.

Declarative Python flows

You declare the desired target state in plain Python functions rather than hand-managing DAGs, state and invalidation.

End-to-end lineage

Every vector, row or graph node traces back to its exact source byte, making pipelines debuggable and auditable.

Many sources and targets

Connectors span codebases, file systems and blob stores, databases, message queues, images, video and transcripts; targets include vector, graph and relational stores, warehouses, queues and feature stores.

Production-grade Rust core

The core engine is Rust, with retries, exponential back-off, dead-letter queues and failure isolation so one bad record does not stall the flow.

Ready-made examples

20+ working starters: real-time code indexing with AST chunking, PDF-to-RAG, conversation-to-knowledge-graph, structured extraction, podcast transcription graphs and CSV-to-Kafka streaming.

Ejecútalo tú mismo

  1. Clone the repository

    Clone CocoIndex for the examples tree; most users install the package from PyPI instead.

    git clone https://github.com/cocoindex-io/cocoindex.git
    cd cocoindex
  2. Install the package

    Install CocoIndex into your Python environment.

    pip install -U cocoindex
  3. Run your first flow

    Define an App that walks a docs folder, chunks and embeds it into Postgres, then run its update - re-runs only process the delta.

    python main.py  # your flow file - see the README quickstart for the exact code

Preguntas frecuentes

Who maintains CocoIndex?

CocoIndex is developed by cocoindex-io and open-source contributors, with an additional Enterprise offering for very large corpora.

Is CocoIndex free?

Yes. The open-source engine is Apache-2.0 licensed.

Does it need a paid API key?

Only for the models you choose in your transformations: local embedding models need no key, while hosted LLM or embedding APIs use your own credentials.

How does CocoIndex compare with Airbyte, Dagster or a cron embedding script?

Those move or schedule batch jobs; CocoIndex is a stateful incremental engine that tracks per-record provenance and recomputes only the delta when sources or code change.

How do I get started?

Run pip install -U cocoindex and copy the quickstart flow: declare a source, a splitter, an embedding target, and run the app.
