sparkql ✨: Apache Spark SQL DataFrame schema management for sensible humans [2020-ongoing]
A lightweight Python library that provides literate schema management for PySpark (Apache Spark). Designed for developers who regularly work with PySpark’s SQL DataFrames, part of Spark’s module for structured data processing. From personal experience, PySpark’s native support for schema definition can become hard to read and manage in real-world projects. sparkql provides an ergonomic interface to DataFrame schema management.
