situation.Active Master-master replication has some special uses. For example, two parts that are geographically distributed require a copy of their own writable data. The biggest problem with this structure is the update conflict. Assume that a table has only one row (one column) of data, with a value of 1, and if two servers execute the following statements, respectively:Execute on the first server:mysql> UPDATE tbl SET col=col + 1;Execute on the second server:mysql> UPDATE tbl SET col=col *
