Is this useful for complex joins?

Absolutely. It helps identify inefficient join orders and suggests more performant alternatives to reduce temporary table usage.

Does it support different database engines?

While it focuses on standard SQL performance patterns, it is highly effective for PostgreSQL, MySQL, and similar relational databases.

How does the skill analyze my queries?

It processes your SQL query and its EXPLAIN plan to map out execution steps and identify high-cost operations like full table scans.

Can it suggest specific indexes?

Yes, the skill identifies columns that would benefit from indexing based on your filtering and join conditions.
