can't get data from a slave server after write data to master server via readwritesplit router.

I setup my web server with router=readwritesplit.

My application, content management system, operates like that a user enter a new entry with a title then the application send email soon with it's title.
The application can't get the title from database because of the slave server has delayed.
The application can get the title from database a little while after.
I want maxscale to automatic delay in this situation.
