Subject Questions on compound file format
Date Thu, 04 Sep 2008 20:02:45 GMT

What are the benefits/drawbacks of using the compound file format
(<useCompoundFile>true</useCompoundFile>)? From searching through Solr and
Lucene wiki pages:

1. Using the compound file format drops the number of file descriptors
needed. Any other benefits?
2. Indexing may be slower. What about query performance?
3. Since Lucene 1.4, the compound file format became the default, however
Solr default is not to use compound file format. Why this inconsistency?
