學習筆記：MySQL Cluster 的binlog

MySQL Cluster中，如果啟用了binlog，在任何sql node的更新操作，都會寫入所有node的binlog，當然，這是有條件的：更新操作的node上binlog_format=mixed或者row，反之，如果是statement，就只會在更新操作的node上寫入binlog。

另外，MySQL Cluster Replication是要求binlog是row-based，所以要將master的binlog設定為mixed或row。手冊中如是說：

Replication of a MySQL Cluster as described in this section and those following is dependent on row-based replication. This means that the replication master MySQL server must be started with --binlog-format=ROW or --binlog-format=MIXED
