Hello,

I'm running a 5.2.1 SolrCloud cluster and I see that one of my cores
is configured under solrconfig.xml to use

<directoryFactory
class="${solr.directoryFactory:solr.StandardDirectoryFactory}"
name="DirectoryFactory"/>

I'm just starting to grasp different strategies for Directory
implementation. Can I assume that solr.StandardDirectoryFactory is a
MMapDirectory as described by Uwe Schindler in this post about the use
of virtual memory?

Thanks!

Best,

Eric Torti
