Datasets

Datasets is a library designed for the management, processing, and sharing of large-scale data collections for machine learning workflows. It functions as both a data processing framework and a versioning platform, providing tools to organize, filter, and transform massive datasets while ensuring reproducibility across research and development teams.

The library distinguishes itself by enabling the handling of datasets that exceed available system memory. It utilizes memory-mapped file access, disk-based caching, and lazy iterative streaming to maintain performance when working with large-scale data. These capabilities allow for efficient data preparation and access without requiring the entire collection to be loaded into physical memory.

Beyond local processing, the project serves as a collaborative repository for publishing and discovering datasets. Users can share data collections globally, facilitating consistent access and versioning across distributed research environments. The library is documented and distributed as a Python-based toolkit for integration into machine learning pipelines.
