Hi, I was trying to clean a database by deleting records of some of its tables. But in our model we have a table that is heavily referenced, that is, many tables reference this particular table by foreign key constraints. We don't have foreign key indexes, so executing a delete from mytable takes

Re: [GENERAL] Update or Delete causes canceling of long running slave queries
