AstrumKDR - Lightweight KDR & Leaderboard
AstrumKDR is a lightweight, performance-focused plugin for tracking Kills, Deaths, and KDR (Kill/Death Ratio) on your server. It is built to be fast, using SQLite for storage and an asynchronous caching system for the leaderboard, ensuring zero lag even on heavy PvP servers.

Features:

• K/D Tracking: Logs all player kills and deaths.
• Efficient Leaderboard: A KDR ranking system that is updated in a cache, without overwhelming your database.
• 100% Optimized: All database writes (kills/deaths) are handled asynchronously. All ranking reads (placeholders) are served from a fast in-memory cache.
• Lightweight: Uses SQLite (local file database), requiring no setup for an external database like MySQL.
• PlaceholderAPI Support: Comprehensive placeholders for both personal stats and the top rankings (see Documentation).

Requirements:

• Spigot/Paper 1.21+
• Java 17+
• PlaceholderAPI (Required)

Installation:

1. Place AstrumKDR-1.0.4.jar in your /plugins folder.
2. Place PlaceholderAPI.jar in your /plugins folder.
3. Restart your server.
4. (Optional) Use the placeholders in your holograms, scoreboards, or menus.
