[hibernate-issues] [Hibernate-JIRA] Commented: (HSEARCH-361) Only index an entity if an indexed property has changed

[j nadler (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-361?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=39436#action_39436 ] 

j nadler commented on HSEARCH-361:
----------------------------------

This has become a significant performance problem in my application.  We have a three-deep list of persistent entities using @IndexedEmbedded (A -> B -> C) where C is a broadly linked 'Category' type of object.   We update 'C' frequently, but the @Field indexed properties almost never change.   In some extreme cases, updating C can cause HSearch to load over 100k A objects for reindexing, even though no data that affects the index has changed.
