A problem about Semi sync RRS feed

  • 问题

  • Our db use Mysql 5.5, and use Semi sync tool to keep master and slave db's data. It works fine. But last week , i found there were more than 100 records in  7 days are have missed in slave db, not all the records. I checked logs on slave and found sql commands had transferred, but not excute. It's very strange and confuese me. I looked around passges on Internet, lots of reasons show me, like network reasons, servers performance and so on . Does any people can tell me the real reason and fast resolution?

    Many thanks!
