Data Resharding and Partitioning

概要

This skill provides specialized guidance for complex data redistribution tasks, ensuring datasets are organized into compliant shards and groups. It focuses on the critical concept of recursive constraint application, helping users avoid common mistakes where directory limits are only applied to leaf nodes. By providing mathematical validation patterns, hierarchical design templates, and verification strategies, it ensures that massive data reorganizations—such as partitioning the C4 dataset—remain structurally sound, verifiable, and easy to reconstruct through metadata mapping.
