    Single / Personal servers
    Simply drop the jar into your "plugins" folder. The auto-generated config should default to reasonable values for you, but you may modify it if you wish.

    Multiple servers / Large networks
    Drop the jar into the plugins folder and configure the "sql" section to use MySQL instead of SQLite. RabbitMQ and/or Redis are optional but highly recommended if you have multiple servers.

    PLEASE NOTE: If you have multiple servers, either use a shared MySQL database or set up Redis or RabbitMQ. Data desync issues will occur if this does not happen.

    API usage
    Code (Text):
    long getCurrentSQLTime();
    void addPlayerData(UUID uuid, String ip, String server);
    void removePlayerData(UUID uuid);
    void removePlayerData(String ip);
    ImmutableSet<PlayerData> getPlayerData(UUID uuid);
    ImmutableSet<PlayerData> getPlayerData(String ip);


    ImmutableSet<PlayerData> data = api.getPlayerData("");
    PlayerData d = data.get(0); // Somehow
    Example - list all players logged into all IPs that a specified player has ever logged in on
    Code (Text):
    ImmutableSet<PlayerData> uuidData = api.getPlayerData(uuid);
    Set<PlayerData> altData = new HashSet<>(uuidData);

    for (PlayerData data : uuidData) {

    altData.removeIf(v -> uuid.equals(v.getUUID())); // This now contains all potential alts, minus the original uuid that was searched for
    Example - emulate Essentials /seen
    Code (Text):
    ImmutableSet<PlayerData> data = api.getPlayerData(ip);
    for (PlayerData d : data) {

    List<PlayerData> sorted = new ArrayList<>(data);
