Pathway Live Data Framework
What Pathway Live Data Framework is
Pathway Live Data Framework is a Python data processing framework for analytics and AI pipelines that work with stored data and live streams. It supports streaming ETL and retrieval-augmented generation (RAG), and a single pipeline can handle both static data and incoming streams. Its Rust engine runs Python code with multithreading and multiprocessing. Differential Dataflow lets it process out-of-order data points in real time, while state persistence can help resume computation after a failure or pipeline update. AI tooling includes online machine learning, RAG pipelines, and vector indexes for fresh data. Pathway includes 350+ connectors, including SharePoint, and users can build their own. Python and SQL programming APIs are available, along with a REST endpoint for serving queries, answers, and real-time features. Deployment options include Docker and Kubernetes, with OpenTelemetry compatibility. The free Community tier is self-hosted and supports up to 8 GB RAM and 4 cores. Scale is self-hosted, requires a license key, and supports up to 16 GB RAM and 4 cores. Enterprise licensing supports self-hosted or managed deployment.
Who it suits
Pathway suits developers building analytics, streaming ETL, or AI pipelines in Python or SQL, especially where the same workflow must handle stored and live data. Its self-hosted Community tier fits smaller deployments within 8 GB RAM and 4 cores; larger deployments can consider Scale or Enterprise.
What it does well
- One pipeline can process static data and live streams.
- Supports Python and SQL programming APIs.
- Includes 350+ connectors and custom connector development.
- Can save computation state for recovery after failures or updates.
- Supports Docker and Kubernetes deployment.
What to know first
- Community is limited to 8 GB RAM and 4 cores.
- Scale requires a license key and is limited to 16 GB RAM and 4 cores.
- Scale license keys send anonymized usage data to Pathway.
- Enterprise pricing is not published.
Limits
The free Community tier is self-hosted and supports up to 8 GB RAM and 4 cores. Scale supports up to 16 GB RAM and 4 cores, is self-hosted, and requires a license key.

As pathway.com lists them, read 4 Oct 2026. The maker's own page has the final word.
Getting started
- Open pathway.com.
- Choose the Community tier for a free self-hosted deployment, or review Scale and Enterprise licensing.
- Build a pipeline using the Python or SQL APIs.
- Deploy with Docker or Kubernetes.
Verdict
Choose Pathway if you need Python or SQL pipelines that combine live data processing with analytics or AI tooling. Community is free within its self-hosted resource limits; deployments needing more capacity can look at Scale or Enterprise, with Enterprise pricing available through licensing rather than a published price.
