Synchronize the player data across multiple servers in a network
This plugin synchronizes a player's data across multiple Minecraft server instances. This is especially useful in a BungeeCord setting, where players want a continuous experience moving between multiple server instances.
This is done by copying a player's data file (world/playerdata/UUID.dat) to a common directory when they disconnect. On reconnection, on the same server or another, the file is copied in place before the server's processes try to read from it. Effectively, the player's data travels with them.
Multiple groups of synchronization on the same network can be done; for example, all survival servers vs all minigame servers. This is possibly by defining different save directories in the config. All of the servers using the same directory will be put in a common pool to share that data.
One notable exception comes from player positions, which must NOT be shared across servers. As such, these are stored separately in data files.
For server owners on POSIX-compatible systems (Linux and others), you can set the player-permissions config value to set the file permissions that the player data should have on saving to the shared directory. Minecraft versions up to 1.20.1 set read permissions to the group; this is no longer the case. This lets you revert this behavior. Don't use unless you know what you're doing, you could break the sync process!
Note that this plugin benefits from an update on each protocol version change (usually game version updates) of Minecraft. It doesn't tend to outright break, but a warning on boot will be shown.
storage-path, which is a directory path. Servers with the same storage-path value will share their player data. Make sure that the directory exists and is writable!storage-path: The directory to use to store the players data. Servers with the same storage-path value will share their player data. If left empty, no synchronisation will happen. This can be useful to have the /switch method available.player-permissions: The POSIX file permissions to apply to the saved player data. Format: rw-r--r--. Defaults to null, applying no changes. Don't use unless you know what you're doing!
/switch: Used by authorized players to change servers. This has to be used instead of BungeeCord's /server to ensure that the player's data is properly saved before the disconnection registers.
iosync.switch: Access to the server switch command.
I use all of my plugins on my own servers, and I like my plugins to be stable, reliable and low maintenance. Breaks on version upgrades are not expected, but should they happen, they will be quickly fixed.
If you enjoy my work, I welcome sponsors! I've been running Minecraft servers since 2011, developed several plugins and tools for server owners, and I'm now working my way through releasing many of them. Your support would go a long way toward encouraging me to put more time and effort into this, plus fix any issues that might be discovered over time!
