Tablestats currently reports output in a mixed format which is neither
ideal for human readability nor machine readability. Spaces are also
inconsistently used and 13 digit numbers w/out commas or larger units are
complicated to read.
For example, 'Bytes repaired / un-repaired / pending' uses KiB, MiB units,
but 'Space used live / total' uses bytes.
Space used (live): 1463210998523
Space used (total): 1463210998523
Bytes repaired: 0.000KiB
Bytes unrepaired: 4315.386GiB
Bytes pending repair: 0.000KiB
Given tablestats supports a machine readable formatting with the -f format
option for json or yaml output, this Jira proposes:
- standardizing the output to be human readable (-H) as default and
- eliminating the current mixed mode of formatting.
The above example would become:
Space used (live): 1463.210 GiB
Space used (total): 1463.210 GiB
Bytes repaired: 0.000 KiB
Bytes unrepaired: 4315.386 GiB
Bytes pending repair: 0.000 KiB
Existing machine readable formatting (with -f) will be unchanged. More
detailed examples can be found in the Jira CASSANDRA-19104 and associated
google spreadsheet detailing the existing and proposed output:
