QueryHandler should use lucene Input-/OutputStream implementations
------------------------------------------------------------------
Key: JCR-189
URL: http://issues.apache.org/jira/browse/JCR-189
Project: Jackrabbit
Type: Improvement
Components: query
Environment: svn revision: 233161
Reporter: Marcel Reutegger
Assigned to: Marcel Reutegger
Priority: Minor
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.
