What advanced database features are covered?

The skill covers advanced techniques like materialized views, table partitioning, and functional indexes to handle high-scale data requirements.

Does it support databases other than PostgreSQL?

While many examples use PostgreSQL syntax, the core optimization patterns and indexing principles are applicable to MySQL, MariaDB, and other relational databases.

Is it useful for initial schema design?

Absolutely; it offers guidance on choosing the right data types and index types during the design phase to prevent performance debt before it occurs.

How does this skill help with slow SQL queries?

It provides systematic patterns for analyzing EXPLAIN plans and implementing the most effective indexing strategies to reduce query execution time.

Can this skill help with N+1 query problems?

Yes, it includes specific code patterns for identifying N+1 issues and replacing them with efficient JOINs or batch loading operations.

Optimizes database performance through systematic query tuning, advanced indexing strategies, and detailed execution plan analysis.

概要

This Claude Code skill provides a comprehensive framework for transforming slow-running database queries into high-performance operations. It guides developers through the intricacies of SQL optimization, covering critical areas such as interpreting EXPLAIN ANALYZE output, selecting appropriate index types (B-Tree, GIN, GiST), and eliminating N+1 query anti-patterns. Whether you are debugging production bottlenecks, designing scalable schemas, or managing massive datasets via partitioning and materialized views, this skill offers the implementation patterns needed to ensure your database layer remains responsive and cost-effective.
