Cross-Server Player Data Sync for Minecraft Fabric Networks
⬇ Download on SpigotArkCrossPlayerData is a cross-server player data synchronization infrastructure for Minecraft Fabric networks running behind Velocity.
It provides a single source of truth for player data across multiple backend servers, preventing inventory loss, duplication exploits, rollback issues, and conflicting writes during server transfers.
Instead of rebuilding player data field by field, ArkCrossPlayerData synchronizes complete vanilla player .dat files, preserving inventories, mod-added NBT, DataComponents, formatted books, and other custom data with byte-level fidelity.
The system uses a Redis hot layer and MySQL cold storage with distributed locking, optimistic version control, and safe handoff protocols to guarantee that each player's data is owned by exactly one server at any moment.
Features include:
Experimental software. Always test with backups before using in production environments.
