1.1 Overview of PawSQL
PawSQL is an enterprise-grade database performance-tuning platform that covers the entire SQL lifecycle—from development and testing to operations. It delivers:

• Automated query-rewrite optimization
• Smart index recommendation
• Rule-based SQL review for DDL,DDL and DQL
• Continuous monitoring & optimization

It supports all major open sourced and commercial engines (MySQL, PostgreSQL, Oracle, SQL Server), providing developers and enterprises with a one-stop solution for innovative SQL optimization.

1.2 PawSQL Community Edition
The PawSQL Community Edition is tailored for individual developers and small teams. It offers a permanently free, self-hosted deployment that you can spin up locally or in your private cloud—no external dependencies required. One-click SQL optimization and built-in performance validation come out of the box. This edition supports MySQL and PostgreSQL, and grants each user up to 600 optimization runs per month, easily covering day-to-day development and testing needs.

2. Core Advantages

2.1 Permanent Free-of-Charge & Self-Hosted

• Forever-free: Same core SQL-review and optimization capabilities as our enterprise edition, ideal for long-term use by individuals and small teams.
• Self-hosted deployment: Available via Docker image or binary package for your local server or private cloud—never send your SQL logs or data to the public internet.
• No extra ops overhead: Deploy on any container-ready Linux host (4 GB RAM, 2 CPU), and you’re up and running.

2.2 Industry-Leading SQL Optimization Engine

The Community Edition ships with the exact same optimization core as our enterprise offering, giving you database-expert-level performance tuning.

Three Pillars of the PawSQL Engine

1. Advanced Query Rewrites

• Built on our in-house parser and rewrite algorithms
• Performs deep AST-level transformations to produce semantically-equivalent, higher-performance SQL
• Implements commercial-grade logical optimizations (predicate pushdown, projection pushdown), plus cost-based rewrites (subquery unnesting, query folding)
