Welcome to Pathway Developer Documentation!

Pathway is a Python data processing framework for analytics and AI pipelines over data streams. It's the ideal solution for real-time processing use cases like streaming ETL or RAG pipelines for unstructured data.

Key Features:

• Easy-to-use Python API: Pathway is fully compatible with Python. Use your favorite Python tools and ML libraries.
• Scalable Rust engine: your Python code is run by a powerful Rust engine with multithreading and multiprocessing. No JVM and no GIL!
• Stateful operations: use stateful and temporal operations such as groupby and windows.
• Incremental computations: using Differential Dataflow, Pathway takes care of out-of-order data points for you, in real time.
• Batch and streaming alike: use the same pipeline on static data and live data streams.
• In-memory data processing: real-time updates, reduced latency, and higher throughput.
• Easy to deploy with Docker or Kubernetes. Pathway comes with an orchestrator and is fully compatible with OpenTelemetry.
• Exactly once consistency: obtain the same results in both batch and streaming.
• Persistence and backfilling: save the state of the computation to quickly resume after a failure or a pipeline update.
• LLM tooling: online ML, RAG pipelines, vector indexes... With Pathway, your ML pipeline works on fresh data.
• Connect to any data source: Pathway comes with 350+ connectors, including SharePoint. Or implement your own.
