[ http://issues.apache.org/jira/browse/JCR-189?page=all ]
Marcel Reutegger resolved JCR-189:
----------------------------------
Fix Version: 1.0
Resolution: Fixed
The changes for this improvement required some changes in the configuration:
- The FileSystem element in SearchIndex is now optional. Whether the
configuration must have a FileSystem element depends on the QueryHandler
implementation. If the QueryHandler does not use a FileSystem, it can be
omitted. Which is now the case for the default Jackrabbit QueryHandler
(org.apache.jackrabbit.core.query.lucene.SearchIndex).
- When using the default Jackrabbit QueryHandler the parameter 'path' is now
mandatory. See sample config src/config/repository.xml
I tried to adapt all config files accordingly (also those under contrib). Hope
I didn't forget any...

>
> Currently the QueryHandler uses a jackrabbit specific implementation of the
> lucene Directory interface to make use of the jackrabbit FileSystem
> abstraction. Lucene operations on the file system however requires quite
> often random access on the index files. With the current FileSystem interface
> / abstraction random access is not possible on a FileSystemResource,
> therefore it is simulated by re-aquiring the InputStream and then seeking to
> the desired position. This it not efficient at all.
> With respect to performance any other use than file based index storage does
> not make sense with lucene. Hence, the current abstraction using FileSystem
> should be dropped in favour of direct file access.
