Description:
It says:
"Number of threads to use when repairing MyISAM tables."

Current description makes it look like you can repair a single table using the number of threads specified, but that is not the case.

If the option is set to anything > 1 then *1 thread per index* is used.

http://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar_myisam_repair_t...

How to repeat:
Look at INSTANCE->Options File->MyISAM

Suggested fix:
The field is a numeric field, but it should be a boolean, aka, either use parallel repair, or don't.

Fixed as of the upcoming MySQL Workbench 8.0.12 release, and here's the changelog entry:

The on-screen description of the myisam-repair-threads system variable was
incomplete. It now indicates that the (default) value of 1 disables
parallel repair (see the MyISAM tab in Administration - Option File).

Thank you for the bug report.
