Stefan Miklosovic updated CASSANDRA-15759:
------------------------------------------
Description:
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.
PR is here [https://github.com/apache/cassandra/pull/566]
