Brad Schoening commented on CASSANDRA-19104:
--------------------------------------------
Ok, I suppose for storage KiB might make sense as the lowest reportable units.
Jacek's example is ambiguous, but I'd say with a leading zero before the
decimal point, there should be three significant digits afterwards, so 0.000 KiB
{noformat}
Example
Bytes repaired: 0.00 KiB
Bytes unrepaired: 4.31 TiB
Bytes pending repair: 0.000 KiB
{noformat}
>From Wikipedia [Significant
>Figures|https://en.wikipedia.org/wiki/Significant_figures]
{quote}[Leading zeros|https://en.wikipedia.org/wiki/Leading_zero]. For
instance, 013 kg has two significant figures—1 and 3—while the leading zero is
insignificant since it does not impact the mass indication; 013 kg is
equivalent to 13 kg, rendering the zero unnecessary. Similarly, in the case of
0.056 m, there are two insignificant leading zeros since 0.056 m is the same as
56 mm, thus the leading zeros do not contribute to the length indication.{quote}

> Project: Cassandra
> Issue Type: Bug
> Components: Tool/nodetool
> Reporter: Brad Schoening
> Assignee: Leo Toff
> Priority: Normal
>
> Tablestats reports output in plaintext, JSON or YAML. The human readable
> output currently has a mix of KiB, bytes with inconsistent spacing
> Considering simplifying and defaulting output to 'human readable'. Machine
> readable output is available as an option and the current mixed output
> formatting is neither friendly for human or machine reading.

> *Not a goal now (consider a follow up Jira):*
> Fix inconsistencies with KiB/MiB/GiB and KB/MB/GB formatting:
> * gcstats - uses MB
> * getcompactionthroughput - uses MB/s
> * getstreamthroughput - uses MB/s
> * info - uses MiB/GiB
