Bill Au commented on SOLR-207:
------------------------------
I confirmed that find -maxdepth does not work on Solaris. So it is back to ls.
We should be OK as long as we don't use any wildcard that causes expansion.
> snappuller inefficient finding latest snapshot

> Key: SOLR-207
> URL: https://issues.apache.org/jira/browse/SOLR-207
> Project: Solr
> Issue Type: Bug
> Components: replication
> Reporter: Yonik Seeley
> Attachments: find_maxdepth.patch
>
>
> snapinstaller (and snappuller) do the following to find the latest snapshot:
> name=`find ${data_dir} -name snapshot.* -print|grep -v wip|sort -r|head -1`
> This recurses into all of the snapshot directories, doing much more disk-io
> than is necessary.
> I think it is the cause of bloated kernel memory usage we have seen on some
> of our Linux boxes, caused
> by kernel dentry and inode caches. Those caches compete with buffer cache
> (caching the actual data of the index)
> and can thus decrease performance.
