[hibernate-issues] [Hibernate-JIRA] Resolved: (HSEARCH-300) Fix documentation on use_compound_file

Fix documentation on use_compound_file -------------------------------------- Key: HSEARCH-300 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-300 Project: Hibernate Search Issue Type: Bug Components: documentation Reporter: Emmanuel Bernard Assignee: Sanne Grinovero Fix For: 3.1.0.CR1 hibernate.search.[indexname].indexwriter.use_compound_file (no tx/batch) Actually I sat down and read more about compound file format. Basically, instead of creating several files representing a single segment, the compound format creates a single file for the whole segment. And you can have a mix of compound and non compound segments for a given index. So you can set different settings for transactional and batch in theory. Not sure why though. Compounds Pro: - less file handlers Compounds Con: - slower at indexing - takes temporarily more space on disk as the uncompound segment is converted to a compound segment when done I don't think this affects the incremental copy so much are segments are essentially read-only. I believe this is not the story we tell to people in the doc, so we need to fix that. Plus it seems the default value is compound = true, just like in Lucene. This is not what we are saying in the doc.
