Pathway
PathwayPython stream-processing and ETL framework on a Rust dataflow engine, unifying batch and streaming under one API with live connectors and production RAG templates. Unlike glue-layer frameworks it is an incremental dataflow engine, keeping vector indexes continuously synced with changing data instead of re-indexing in batches. It runs from a single node to Kubernetes.
The license converts on a fixed future date, which GitHub cannot classify and the openness axis resolves. Verified 2026-08-13 via the pathwaycom/pathway repository.
