Mark Miller commented on SOLR-465:
----------------------------------
bq. But couldn't one start the container with the appropriate system property
pointing to the new NIOFSDirectory class and "turn on" NIOFSDirectory (or any
other Directory) that way?
Yes. Thats why I say its not really broken. It will still work, and you can
still change the impl...but the code implies you will get the right impl for
the right OS, and you won't without using that system property. Hoping to make
that pain go away.
bq. Why not specify in solrconfig.xml?
Possibly...I think automatic has a lot of allure though...
bq. Is it possible to use RAMDirectory too?
The factory returns a Directory, so it is in that sense...it may have other
ramifications though depending on what solr assumes. Don't know off hand.
> Add configurable DirectoryProvider so that alternate Directory
> implementations can be specified via solrconfig.xml

> Solr is presently hard-coded to use the FSDirectory implementation in Lucene.
> Other Directory implementations are possible. This patch creates a new
> DirectoryProvider interface and extends SolrCore to load an implementation of
> it from solrconfig.xml (if specified). If not specified, then it will
> fallback to the FSDirectory.
> A DirectoryProvider plugin can be configured in solrconfig.xml with the
> following XML:
> <directoryProvider class="class.name">
> <!-- Parameters as required by the implementation -->
> </directoryProvider>
> This patch was created against solr trunk checked out on 11/20/2007. Most of
> it is new code and should apply cleanly or with minor relocation. If it does
> not, let me know and I will update.
