@valych: You can use multiple threads if you want to save and load data from a database server, as long as the database server supports multithreading. As soon as you try to use any kind of internal function of the SA:MP server, you will have to let that run on the main SA:MP thread, because otherwise, the server will crash.

Here is a example:

PHP код:

        Thread fetchThread = new Thread(() -> {
            //Fetching my data:
            Map<String, String> locationData = new HashMap<>(); //example
            try {
                Thread.sleep(5000); //simulate workload
                locationData.put("Player1", "Germany"); //example data
                locationData.put("Player2", "Italy"); //example data
                locationData.put("Player3", "Poland"); //example data
            } catch (InterruptedException e) {
                e.printStackTrace();
            }

            Shoebill.get().runOnSampThread(() -> {
                //Do whatever you want to do with the data if it has something to do with SA:MP
                Player.getHumans().stream().filter(player -> locationData.containsKey(player.getName())).forEach(player -> {
                    player.sendMessage(Color.GREEN, "you are from " + locationData.get(player.getName()));
                });
            });
        });
        fetchThread.start(); //Start thread
