Sylvain Lebresne updated CASSANDRA-10677:
-----------------------------------------
Priority: Minor (was: Major)
Reviewer: Stefania
Fix Version/s: (was: 2.1.x)
3.x
Thanks for the patch. Just a heads up however that we won't commit this on the
2.1 branch due to its nature of a relatively minor (the {{folderSize}} method
is not used in a critical path) performance improvement. Marking 3.x
accordingly.
> Improve performance of folderSize function
> ------------------------------------------

> Key: CASSANDRA-10677
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10677
> Project: Cassandra
> Issue Type: Improvement
> Components: Local Write-Read Paths
> Environment: Ubuntu 14. JDK 7
> Reporter: Briareus
> Priority: Minor
> Labels: patch, performance
> Fix For: 3.x

> Attachments:
> Optimized_folderSize_function_to_use_Java_7_nio_walkFileTree_method_.patch
>
> Original Estimate: 2h
> Remaining Estimate: 2h
>
> FileUtils.folderSize function recursively traverses the directory tree using
> listFiles method. This is no longer efficient as Java 7 offers much better
> Files.walkFileTree method. It makes the method work twice faster according to
> my tests.
