About
The Database Sharding Manager skill provides a structured framework for Claude to manage complex horizontal partitioning tasks across SQL and NoSQL environments. It guides developers through a comprehensive five-step lifecycle: assessing current bottlenecks, designing optimal sharding architectures, implementing changes in staging, validating performance against baselines, and executing production deployments. By combining automation scripts for PostgreSQL, MySQL, and MongoDB with best-practice documentation, this skill helps teams distribute data across nodes while minimizing downtime and operational risk.
