Pathway
PathwayPython ETL/stream-processing framework on a Rust dataflow engine, unifying batch and streaming under one API with production RAG/LLM templates and live connectors. Unlike glue-layer frameworks it is an incremental dataflow engine - it keeps vector indexes continuously synced with changing data (real-time RAG) instead of batch re-indexing.
