Subject [jira] Updated: (LUCENE-550) InstantiatedIndex - faster but memory consuming index
Date Tue, 13 Mar 2007 02:24:10 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-550?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Karl Wettin updated LUCENE-550:
-------------------------------

    Attachment: trunk.diff.bz2

Patched contrib/benchmark to support InstantiatedIndex.

Fixed a bug with mergeFactor.

Reverted java 1.5<G> changes in PriorityQueue to (ClassCasting). (This is actually a
spell checker thingy, but due to local dependencies the changes are located in this patch).

Removed write locks. These had severe bugs and need to be reconsidered. Should be back in
next patch. Using multiple InstantiatedIndex:es as segments on a MultiReader rather than updating
the same index, this can be made completly lockless.

> An non file centrinc all in memory index. Consumes some 2x the memory of a RAMDirectory
(in a term satured index) but is between 3x-60x faster depending on application and how one
counts. Average query is about 8x faster. IndexWriter and IndexModifier have been realized
in InterfaceIndexWriter and InterfaceIndexModifier. 
> InstantiatedIndex is wrapped in a new top layer index facade (class Index) that comes
with factory methods for writers, readers and searchers for unison index handeling. There
are decorators with notification handling that can be used for automatically syncronizing
searchers on updates, et.c. 
> Index also comes with FS/RAMDirectory implementation.
