What does the red and white dashed line in query editor represent?

[bchager6]

Does anyone know what the red and white dashed line represents in query editor? I assume it means that something needs to be addressed, but I am not seeing any errors.

Whatever it was, it disappeared. Thanks for the info on those column metrics though. I hadn't used them before.

Probably the same transient error I've run into that a refresh fixes.

The green dashed line means there are errors. What does your Column Quality and Column Distribution say? Turn those on. I haven't seen the red dashed line yet, other than when I was making changes so fast it was just an error in the computation of that box. The fix was to select another query then go back to what i was working on, or force a refresh.
