学习笔记：MySQL Cluster 的binlog

MySQL Cluster中，如果启用了binlog，在任何sql node的更新操作，都会写入所有node的binlog，当然，这是有条件的：更新操作的node上binlog_format=mixed或者row，反之，如果是statement，就只会在更新操作的node上写入binlog。

另外，MySQL Cluster Replication是要求binlog是row-based，所以要将master的binlog设置为mixed或row。手册中如是说：

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
