Stats Command

This mod allows players to view statistics view leaderboards for any tracked metric in the game. It is engineered for scalability, utilizing memory-mapped files and incremental indexing to ensure zero impact on server performance, even with potentially tens of thousands of unique player files. It uses the built-in vanilla stat system and can show stats for any player that have, at any time, been playing on the server.

Features

• Instant Lookups: specific stats for any player (mined, crafted, broken, killed, dropped, etc.).
• Leaderboards: View top rankings for any category with /stats top.
• Custom Stats: Support for custom statistics registered by datapacks.
• High Performance:
  • Uses memory-mapped I/O for nanosecond-level access times.
  • Non-blocking, incremental indexing system.
  • Zero main-thread lag, suitable for large production servers.
