4py
4py is an open-source Python toolkit designed to streamline the development of data-processing pipelines and modular applications. It emphasizes a four-stage processing model, enabling developers to define input, transformation, aggregation, and output stages within a single, cohesive API. The project aims to be lightweight, portable, and easy to integrate with existing Python codebases.
Core features include a minimal runtime that handles task scheduling and error propagation, a collection of
Implementation: 4py is primarily written in Python, with critical performance paths implemented in Cython and optional
Usage and ecosystem: Users typically install via pip, import 4py, and build pipelines by chaining operators.
Limitations and reception: As a lightweight toolkit, 4py may not match the performance of optimized, lower-level
