MySQL clusters - sync a table I've been developing a software that runs on hardware and now I need to synchronise DB on them, but only partly - several tables using MySQL Clusters(don't matter which style), each of hardware can act as a node, and we have virtual one as NDB_MGM.
For ex, I have two tables in DB: users and rules. 
Users should stay unique to each node, but rules should be synced.

My question is: is it even possible?
Yes, this is not difficult: Just create the users table using a different storage engine than NDB.


  It is possible to create tables using other storage engines (such as
  InnoDB or MyISAM) on a MySQL server being used with an NDB Cluster,
  but since these tables do not use NDB, they do not participate in
  clustering; each such table is strictly local to the individual MySQL
  server instance on which it is created.
