   1 when checkpoint, every time `loadCluster`, we will `new InfoSchemaDb`, the id for `InfoSchemaDb` will more and more larger，and finally will larger than 10000
   2 when InfoSchemaDb id larger than 10000 and call `idToDb.put(db.getId(), db)`, the InfoSchemaDb meta will overwrite the  normal db meta, (such as, the  normal db id is 10001),so the normal db meta will lost when checkpoint generate the image file by `saveDb`.
