How does this skill help with slow queries?

It guides you through analyzing execution plans (EXPLAIN) to identify bottlenecks and suggests specific indexing or query restructuring patterns to fix them.

Does it support multiple database engines?

Yes, while focusing heavily on PostgreSQL, it covers universal SQL optimization concepts applicable to MySQL, MariaDB, and other relational databases.

Can it help with ORM performance issues?

Absolutely; it provides patterns to solve common ORM problems like the N+1 query anti-pattern and inefficient offset-based pagination.

What indexing strategies are included?

It covers B-Tree, GIN, GiST, BRIN, composite indexes, partial indexes, and covering indexes to ensure the most efficient data retrieval.

Is it suitable for large-scale data?

Yes, it includes advanced techniques like table partitioning and materialized views specifically designed for managing and querying large datasets efficiently.
