----------------------------------------
> Platform independent implementation of DirectorySizeCalculator and refactor
> ---------------------------------------------------------------------------
>
> Key: CASSANDRA-12019
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12019
> Project: Cassandra
> Issue Type: Sub-task
> Reporter: Joshua McKenzie
> Assignee: Joshua McKenzie
> Priority: Minor
>
> On linux, simplify to
> {{Arrays.stream(path.listFiles()).mapToLong(File::length).sum();}}
> It's simpler and performs better, however is much slower on Windows.
> See discussion on CASSANDRA-8844.
> Also:
> bq. I don't get the DirectorySizeCalculator. Why the alive and visited sets,
> the listFiles step? Either list the files and just loop through them, or do
> the walkFileTree operation – you are now doing the same work twice. Use a
> plain long instead of the atomic as the class is still thread-unsafe.
> So the existing class could use a refactor as well.
