Does it provide solutions for the N+1 query problem?

Absolutely. It includes specific patterns for refactoring N+1 query loops into efficient JOINs or batch loading operations to significantly reduce round-trips to the database.

Can I use this for databases other than PostgreSQL?

Yes. While many examples focus on PostgreSQL, the core optimization concepts—such as B-Tree indexing, batching, and JOIN optimization—are applicable to MySQL, MariaDB, and other SQL-based systems.

Is this skill useful for high-level schema design?

Yes, it covers proactive design patterns like table partitioning, materialized views, and choosing appropriate data types to ensure performance from day one.

How does this skill help identify slow SQL queries?

The skill provides a structured approach to analyzing EXPLAIN plans, helping you identify Seq Scans, high-cost operations, and areas where indexes are missing or underutilized.
