[jira] Commented: (SOLR-1379) Add RAMDirectoryFactory

["Alex Baranov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-1379?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12746508#action_12746508 ] 

Alex Baranov commented on SOLR-1379:
------------------------------------

Moreover, with the RAMDirectoryFactory provided by this patch updating documents via Solr doesn't work properly.

Example of the scenario in which this RAMDirectoryFactory is usable is when persistent (on file system) index is created/updated by another application (perhaps using pure luce approach to maintain this) and Solr core is reloaded whenever updates should affect the search. One of the possible reasons to use this scenario is to speed up search with RAMDirectory when index changes rarely on doesn't change at all.
