Then I checked /and many others/init.d and found script named mysqld which listed approach name: mysqld and prog=mysqld

I don’t have a solution re: doublewrite buffer, but I do realize that Other individuals have verified identical. Just one adjust Facebook created in their branch was to jot down only spaceid/web page selection for the doublewrite buffer, that makes lots of perception for them with semi-sync replication. It would be interesting To judge how this modifications effectiveness properties.
