How does it assist with query plan analysis?

It provides guidance on interpreting EXPLAIN output, helping you identify sequential scans, high-cost joins, and opportunities for index-only scans.

Does this skill help with PostgreSQL and MySQL?

Yes, while many patterns are universal to SQL, it includes specific syntax and optimization strategies for both PostgreSQL and MySQL.

Does it cover advanced scaling techniques?

Yes, it includes patterns for high-level optimizations like table partitioning, materialized views, and concurrent index rebuilding.

Can it help me fix N+1 query problems?

Absolutely. The skill provides specific code patterns to transform N+1 query loops into efficient batch loads or JOIN-based operations.

What is the SQL Optimization Patterns skill?

It is a specialized capability for Claude Code that provides patterns for query tuning, advanced indexing strategies, and database performance optimization.
