Create index for one-to-one relationships

When I upgraded Studio, it now asks whether I want to “Create index for one-to-one relationships”. Not sure why this new message is suddenly appearing. I could use a bit of advice. Should I go ahead and enable it? Is there a downside to this?

Thanks
Eric

Hi,
The feature was implemented in the new version of Studio. So when a project created with a previous version is opened, the dialog occurs. This option is enabled in newly created projects. But if you do not need it - chose “Disable”.

You can change the decision later by editing the studio-settings.xml file in your project.

Or on the Help->Settings->Studio functionality settings screen.
