Query Plan Analyzer అంటే ఏమిటి?

A query plan analyzer takes the output of EXPLAIN or EXPLAIN ANALYZE from your database and visualizes it as an interactive tree diagram. Each node represents an operation (scan, join, sort) with its cost, rows, and execution time.

This tool helps you identify performance bottlenecks in your SQL queries by highlighting expensive operations, sequential scans on large tables, and missing indexes. It supports PostgreSQL and MySQL EXPLAIN formats.
