> Project: Cassandra
> Issue Type: Improvement
> Components: Feature/Virtual Tables
> Reporter: Stefan Miklosovic

> It would be very handy to have a percentage column in
> system_views.sstable_tasks which would say how far a respective task is.
> Indeed, there are currently "progress" and "total" columns but honestly, for
> every day usage, it is rather strange to expect that humans will divide these
> numbers in head if they want to roughly know what the overall progress is.
> One just does not have a rough estimation of the task progress when he is
> presented with two quite big numbers and to estimate the progress from the.
> In the following output, the field "progress_in_percents" is introduced.
