Benjamin Lerer commented on CASSANDRA-15234:
--------------------------------------------
Some high leve comments:
* I would prefer to avoid reading twice the configuration file if possible. It
should be possible to replace {{YamlConfigurationLoader.readStorageConfig}} and
{{isConfigFileValid}} by some checks in {{getProperty}} or by using the
specific converters. As a side note: {{isConfigFileValid}} checks twice for the
same condition on each of the {{if}} conditions.
* The patch can be simplified by making {{Converter}} an {{enum}}. It will
allow to use the enum value directly into the {{Replaces}} annotation. Doing so
will remove the need to use reflection to instantiate the conveters and the use
of a cache to avoid multiple instantiation.
* The change in {{ConfigurationException}} are from some experimentations and
should be removed.
* I would as discussed previously defer the date of removal and remove
{{scheduledRemoveBy}} from the {{Replaces}} annotation.
* It would be nice to have more javadoc on the new code.

> Project: Cassandra
> Issue Type: Bug
> Components: Local/Config

> Priority: Normal

> We have a bunch of inconsistent names and config patterns in the codebase,
> both from the yams and JVM properties. It would be nice to standardise the
> naming (such as otc_ vs internode_) as well as the provision of values with
> units - while maintaining perpetual backwards compatibility with the old
> parameter names, of course.
> For temporal units, I would propose parsing strings with suffixes of:
> {{code}}
> u|micros(econds?)?
> ms|millis(econds?)?
> s(econds?)?
> m(inutes?)?
> h(ours?)?
> d(ays?)?
> mo(nths?)?
> {{code}}
> For rate units, I would propose parsing any of the standard {{B/s, KiB/s,
> MiB/s, GiB/s, TiB/s}}.
> Perhaps for avoiding ambiguity we could not accept bauds {{bs, Mbps}} or
> powers of 1000 such as {{KB/s}}, given these are regularly used for either
> their old or new definition e.g. {{KiB/s}}, or we could support them and
> simply log the value in bytes/s.
