PostgreSQL Index Optimization Toolkit

Unused indexes are silent performance killers — they slow down writes, waste disk space, and bloat production DBs.

This toolkit helps Backend Engineers & SREs quickly identify and safely remove unused PostgreSQL indexes using real metrics, visual dashboards, and automation — no guesswork, no production risk.

✅ Why You'll Love This

⏱ Save hours of trial-and-error index tuning

💡 Make safer performance decisions backed by real data

🚀 Improve write throughput and reduce index bloat

🧠 How It Works

This toolkit integrates seamlessly into your existing stack. Here’s how you use it:

1. Connect to your PostgreSQL database
2. Run the collector script to log index usage metrics
3. Automatically ship logs using Filebeat
4. Visualize index usage trends with the included Kibana dashboard
5. Use the cleanup checklist to review & drop safely
