pt-table-sync script

Hi Magesh,

As per the documentation, “When there is no unique key on the table, there is no choice but to change the data on the slave, and pt-table-sync will detect that you’re trying to do so. It will complain and die unless you specify --no-check-slave”

http://www.percona.com/doc/percona-toolkit/2.1/pt-table-sync .html

Generally, its unsafe to make changes on slave directly but if you don’t have any other way, you have to use --no-check-slave option. Because by default, pt-table-sync will always give error when there is no unique index on table.

Have you tried to use that option? are you facing any issue with that?
