Aleksei Zotov commented on CASSANDRA-16976:
-------------------------------------------
I dug deeper to unit stuff and I feel the current unit logic makes sense.
Possible units are: bytes, ranges, keys. They are applicable to different
compaction types. So "bytes" unit is not a measure of size (like byte, KB, MB,
etc) for progress/total, but rather is a sing that the numbers in
progress/total columns are measured in size (not a number of keys or ranges).
Basically that's why there is this condition that we need to convert
progress/total to human readable size format only if "size measurement" is
applicable:
boolean toFileSize = humanReadable && Unit.isFileSize(unit);
Even though the current logic seems to be reasonable, "unit" name is confusing.
Maybe we can rename "unit"... For example: "compaction unit" - it does not
clarify a lot what it is, however, it highlights it is not just a size unit.
WDYT guys?

> Currently there is a difference in the output if {{nodetool compactionstats}}
> command and {{sstable_tasks}} virtual table (originally introduced by
> CASSANDRA-14457). They need to be aligned. The differences are:
>
> ||nodetool||VT||Comment||
> |percentComplete|completion_ratio|column naming is different only|
> |completed|progress|column naming is different only|
> |compaction type|kind|column naming is different only|
> |sstables|NA| |
> Additionally, please, update necessary documentation.
