Bilateral synchronization of database on MySql

There is a small MySQL database and there are 5 offices that connect to this database and add new information to it. The database program is written in C#.

For technical reasons, you have to keep a copy of the database on all computers and synchronize with the main database every few minutes. Accordingly, this two-way asynchronous synchronization of MySQL databases needs to be implemented.

Almost all the data of the offices can not intersect, so this will greatly simplify the task.

We need to add synchronization functions to our program. If you can not make the main database the one that is hosting, because There is turned off logs, then you can transfer it to my home server and configure there as you like.
