Can it help with ORM-related performance issues?

Yes, it specializes in detecting N+1 query patterns in ORMs like Prisma, TypeORM, and SQLAlchemy, offering implementation patterns for eager loading and batching.

How does this skill help with slow SQL queries?

The skill analyzes execution plans to identify bottlenecks like full table scans or inefficient joins, then provides optimized query rewrites and specific indexing strategies to improve speed.

Can this skill help with database migrations?

Yes, it provides strategies for zero-downtime migrations, including schema versioning, large table refactoring, and rollback procedures for high-availability systems.

Does it support cloud-specific databases?

Absolutely. It includes specialized knowledge for optimizing AWS Aurora, DynamoDB, Azure SQL, and Google Cloud Spanner, focusing on both performance and cost reduction.
