It would be good to have columns that can be derived from other columns.

Examples would be a column that's A-B, (A+B)/2, or A-A'. It would only work on numerical columns.

Thanks for issue. Shouldn't be this issue be in the mainline eclipse-tracecompass?

I see this feature needing "incubation" before getting it right. But yeah, sure!

Not sure if that can do it without updating the events table implementation and related code of mainline. Otherwise it's fine to have it here.
